In former times there was a box kept by the session-clerk, and from time to time examined by the clergyman and elders, in which was deposited all the contributions of the parish, whether collected at the church door or by the deacons.  The money contained in this box was primarily intended for the poor, but it was also applied to such ecclesiastical purposes as the session might approve of.  In the beginning of 1646, for instance, about L.200 Scots was applied in repairing the church, and taking down the old parish church; and afterwards the damage done by Cromwell and his soldiers to the church seats and place of public repentance was remedied from this source. The amount contained in the box in November 1646, was L.208 Scots.

A large additional parochial fund was afterwards obtained in the following manner: Marion Corstorphine, a foundling, who belonged to, and had been bred up from infancy in the parish, was servant to a gentleman of extensive property in the vicinity of Edinburgh.  Her master, in July 1753, had, after having tied her hands and feet, beat her with a horse whip in a most barbarous manner, to the great effusion of her blood, and he then placed her, stripped of clothing, in a dark cellar, where she was detained during the whole night, and no one allowed to come near her.  On escaping from this savage treatment, she applied to Mr. George Fordyce, the minister of Corstorphine, for protection and redress.  He at once took up the case, and having threatened a criminal prosecution, the matter was speedily compromised by the master, who agreed to pay immediately L.100 Sterling, which Mr. Fordyce apportioned as follows, viz. L.50 to Marion, L.25 to the poor of Corstorphine Parish, L. 10 to the poor of another parish where the outrage had been committed, and L.15 to the Infirmary of Edinburgh; and afterwards to pay Marion L.10 Sterling, yearly, until her marriage, and upon that occasion an additional sum of L.100 Sterling.

This foundling, in return for the interest taken in her by the minister of Corstorphine left her whole means to the poor of the parish, and, accordingly, on 14th December 1768, we find that the poor's funds amounted in value to L.579, 8s. 4d. Sterling.

The funds belonging to the poor at present are as follows, viz: 1. Sum in bond to road trustees, L.250; 2. Legacy from the late A. Keith, Esq. L.100; 3. Do. from the late Captain Charles Hope Watson, L. 100; total, L. 450.

The number of the poor in 1709 was only 5, and the amount paid for their maintenance monthly by the session was L.4, 9s. 6d. Scots.  The number at present on the list of paupers is 38 while the sum annually raised by assessment, collections, interest of the funds and other sources, amounted in 1838 to L.299, 15s. Sterling.

The bell of the church has the following inscription on it: "Sir James Forrester of Corstorphine gifted me to this kirk, anno 1577, and the heritors of Corstorphine renewed me anno 1728.'' The weight of the old bell here referred to was 302 lbs., which the heritors sold for L.136 Scots.  The present bell weighs 384 lbs., and the price of it, with the wheel and whole appendages, was L.436 Scots.
