I have received some information from Robert McKee who graciously accepted the expense and time to provide copies of published material on Thomas McKee. Robert writes: The enclosed copies are all that I have on Alexander and Thomas McKee. Around 1956 or 1957 I was subscribed to men's magazine called "Argosy". They had a story in there about Alexander McKee and a fellow named Malden who were counterspies in the American army for the British. After the war of Independence they had a price on their heads and escaped to Canada where they were awarded land grants in Essex County, Ontario for their service to the crown. I am assuming that this is the branch that my family came from. Also I have an aunt that visited the Mission in Carmel California many years ago and told me there is a painting of a Spanish lady there by the name of "McKee". The address is Mission San Carlos Borromeo, 3080 Rio Road, Carmel, California 93923. Hope this stuff is useful to you, tho you may already have some of the info. R McKee.
The first item from Notes and Queries, Historical and Genealogical, Chiefly relating to the Interior Pennsylvania Published Baltimore, Genealogical Publishing Company 1970.

In Notes and Queries, No. xliv, mention is made of Thomas McKee. Was this the same man who gave name to the first river falls above Harrisburg, and was the owner of a farm about a mile above Maclaysburg, known forty-five years ago as the McKee farm. The journey of Bishop Cammerhoff was over a country with which I was once familiar. McKee must have lived at that time on or near the site of Georgetown, above the Mahontonga creek. But to me the most interesting statement of the Bishop is the reference he makes to McKee's Indian speaking wife. The inference, the reader would draw from it would be that she had been a white captive and did not know English. That she was of pure Indian blood, allow me to submit and item or two of circumstantial evidence.

Early in my boyhood I once heard my father detail to a guest the story of this same Thomas McKee and his wife, but I do not recollect that he made any statement, as to how and by what means he had obtained the information.

The business of Indian trading in the first half of the eighteenth century was free to all, upon receiving a license therefor, and to young men of enterprise or who preferred a vagabond life with its risks and projects, it had glorious attractions. McKee had early entered into the trade and to make his success the more certain had acquired a knowledge of the Delaware language. Young and reckless, perhaps, he pushed his trade far into the wilds of the Susquehanna. Here he ventured into a camp of strange Indians and met, as it happened with a warm reception. Those unsophisticated children of nature did not see the necessity of paying furs and hides for what they could grab at will. They took him in, confiscated his pack train and goods, and as he demurred or perchance abused them somewhat, they held a council and decided to burn him, and so finish the whole business. In order to have a good time of it, they postponed the frolic until the next day and in the meantime sent out runners to invite their distant friends to come and enjoy with them the honors of the fire festival. To make everything solid they bound McKee to a tree, and to fill up the vacant interval, they held an orgie over his whisky, whilst that unfortunate individual, helpless as possible, lay and waited for his doom.

It is night, the moon shone down on the tall pine forests, and the revelers beneath it , and on the captive at the foot of the tree; but whisky is not respector of persons; in this case it did its work effectually. One after another those doughty warriors succumbed to its gentle influences, and soon the whole camp was in a profound sleep. But McKee slept not; he saw his opportunity, but it was in vain; by no means could he contrive to untie or release himself. In despair, he resigned himself to his fate and actually fell into a doze of sleep. What were his dreams or wandering thoughts will never be known, but a hand pressed his shoulder and he awoke. It was to see and Indian girl leaning over him, as the bright moonlight fell upon his anxious face. Why she took an interest in him may never be known, but there she was, and as fortunately he could talk to her, he piteously begged of her to release him. She shook her head; if she did, she would have to bear the vengeance of her people. "Then, go with me, and we will escape together, you shall be my squaw and shall live in a house and wear rings and ribbons." "Would he make her his squaw the same as a white mans squaw?" McKee solemnly promised, and she cut him loose. They made good their escape together and to his honor, be it said, fulfilled his promise, he legally married her, and lived with her all his days a prosperous man.

McKee, as stated, held a commission in the British army, and probably drew half pay. British gold had crossed his hand, and in his later days he felt no interest or sympathy in the cause of independence. He was a royalist, his neighbors called him a tory, a man which then bore with it undpeakable bitterness. His lands were not confiscated. (Hiram Rutherford)

Here is a portion of an article called "McKee: Indian friend or foe"? by David Quintner, Star Staff Reporter.

He is Sandwich's most influential son, but few in the area of the old town have ever heard of him. He helped shape the land called Canada, yet no major encyclopedia mentions the man or his achievments.

He was Alexander McKee, the Irish-born adventurer who pulled off one of the greatest real estate deals in British history.

He emerges from a shadowy past with the display at the Hiram Walker Museum of a recently restored portrait believed to depict McKee as a young bandsman.

The discovery of the painting in a California movie actors home, and its eventual return here to the land of McKee's greatest triumphs, is a saga of speculation and science, and the fulfilment of a Windsor historians dream

The 22-by-27 inch painting restored last year at the Canadian Conservation Institute in Ottawa, may conceal beneath its ancient canvas patching and layers of old paint, more clues about the man who was a friend of George Washington (who later put a price of 300 pounds on his disloyal head for choosing the Crown over the fledgling American Nation) and much later a close friend of John Graves Simcoe, governer of Upper Canada.

If much about the man is mysterious, his great land buying sprees with the Indians are not. Noteworthy for their colossal cheek, those deals- gave political form to much of what later became South-western Ontario.

Philadelphia author and historian Patricia Talbot Davis has been following McKees trail northwards from Pennsylvania to this region, where he died in 1799.

Indian Wars of 1763 and 1764, Letter from Thomas McKee to William Johnson.

Hon. Sir: My son returned home the 1st Inst., when I was honoured with your Warrant, Instructions and Favour of the 3d January. I was extremely sorry to hear of your Indisposition and sincerely hope you find a speedy Recovery.

I make no doubt but my son at that time informed you of the Conduct of the Frontier Inhabitants of this province who murdered six Connistogo Indians at their town near Lancster, being all that were at Home at the time except two boys who made their escape from them. The remaining Part fourteen in Number, Women and Children being dispers'd through the country were seized by the Sherriff and Migistrates of the County and confined in the Work House of Lancaster, in order to guard them, but upon the back Inhabitants receiving information of this, they again assembled themselves in a Body and came down armed to Lancaster, broke open the Work house and in most inhuman manner butchered the whole, sparing neither Women or Children, and action I look upon not inferior to any of the cruelties committed by the Savages since the Commencement of the late or prefent War. As to my Knowledge these Indians have lived all their lives within eight miles of Lancaster, in peace and Quietness with their Neighbors, and I do not beleive were ever concerned against us.

The Government made some faint efforts to find the Heads of these people, which only encourage their Impudence, as I am informed a few days ago, to the Number of three hundred assembled themselves in Arms and came down to Philad in order to cutt off some Indians the Government have here, but upon some Promises being made them by the Government, they have dissuaded them from murdering those in Philad and they are return'd Home again, and they now carry things to great length as to threaten the lives of sundry private people who have not agreed with them in opinions but condemned this as a moft detestable murder, and not only contrary to the laws of the government, but Christianity, and everything that ought to distinguish us from Savages, as this leaves us no room to find fault with their killing our innocent People in cold blood. Blood, as they may now say we are facilitated in the same manner on them. I should be far from enpowering their cause, I not think they were innocent, as no person has suffered more by the savages than I have done, and I should have thought the people who have thus behaved more exusable if they had cutt off in Philad maintained at the Public Expense, as there is some reason to believe that some of these have acted against us. But the others in a manner were become white people, and expected the same protection from us. I thought proper to acquaint your Honor with this Affair, as you might perhaps want to acquaint the Indians with the true circumstances relating to it.

My son presents his Compliments to your Honour and begs if you have not sent a Warrant for his Acc that you would be so kind enough to forward one soon as it may be convenient to you and if it likewise suits your Conveniency I should be glad your Honour would accompany it with one to me for some Money, as I am really at present in Necessity.

I have nothing further to add, but that I am with greatest Respect, your Honours most obedient and very humble servant. (This is signed Thomas McKee with a bit of flair).

The following by RWM, from Book of McKee which has a chapter devoted to Alexander. Exerpts follow: COLONEL ALEXANDER MCKEE, Deputy Superintendent and Deputy Inspector General for the Provinces of Upper and Lower Canada and the Frontiers thereof, of Indians and their allies; Formerly Crown Deputy Agent for Indian Affairs at Fort Pitt, and subsequentley Detroit. Born 1720-38. Died January 5, 1799

There is some intimation that this distinguished member of our clan was christened Alexander Thomas McKee, or Thomas Alexander McKee. Descendants persistently refer to him so, but for tranditional reasons alone. No documents he signed that the author has seen bear other than the name Alexander or the intitial "A" preceding his surname, nor did any documents that name him refer to him so.

He was born sometime between 1720 and 1738, apparently, as he held the rank of ensign in 1756, and was promoted to a lietenancy in 1757, while yet in his teens. If he were, say 19 in 1757 he would have been born in 1738, and only about 61 when he died in 1799. One accounts states positively that he died of lockjaw January 13, 1799 but a letter from Lieutenant Prideaux Selby to James McKee at Chartiers. Pennsylvania, under date of January 10, 1799 says that he died January 5, 1799. This is so positive that I had accepted it, particularly since it was to this man that Colonel Alexander entrusted his will. However, even this is not conclusive. On October 17, 1957, GW Spragge, Archivist of Ontario, wrote to me as follows:
"The exact date of Colonel McKee's death is probably of little importance except that one likes to get such details correct if possible. I spent just a minute or two onthe matter when I received your letter and I am confirmed in my belief that the date was the 15th"
