According to info pulled up by my aunt I may have further info on William Ludlam married to Betsy Haines.  Our info shows a possible name change with this lineage as well as a dughter of these two being Nancy M. Ludlow  (Ludlam?)  born-?  died 10 Oct. 1864  Peapack  NJ.   She married John Smith.   This leads to my maternal side.
 
The name change I mentioned  looks like it took place  with  Jeremiah Ludlow son of Henry and  Rachel Halsey.

All of the info youshow on your site matches very close with info we have .

I would like to correspond with you moe on this.
