I was very happy to see this message posted! My ancestors are Mary Abrams and Tertellus Hinkley (there are many spelling variations in the records for Tertellus, Tartalus, Turtullus).
What are your sources and references for Mary Abrams, born before 1774 being the daughter of Capt. Hendrick Vanderhoof and Sarah Doremus?
Bush Abrams may be the same as Bush Abrahams listed in the 1810 NY census for Northumberland, Saratoga County. (The index has "Berth" listed as first name, but image looks like Bush). Bush is neighbor of Nathan Hinkley and also 2 doors down from Tart Hinkley, who appears to be living with his new wife, Mary Abrams. 1820 NY census for Wilton, Saratoga County, has a Bush Abrahams and a Abraham Abrahams listed.
