Below in my overview of the family of Hendrick Vroom and Gerritje Staats.Based on Gerritje's age, they could have been married as early as 1734.If her daughter Jannetje married Jacob Boice, Sr., then she would have to be born before 1739.Based on the order the children were listed in the will, Jannetje was born before Lummetie who was baptized in 1746, but I don't know any further than that.

George Boice the Loyalist was the son of Jacob Boice thel Loyalist.
The children of Jacob Boice and Jannetje were as follows: 1) George, baptized 06 Dec 1755 at the First Reformed Church of New Brunswick, NJ 2) Peter, probably the child baptized on 23 Apr 1758 at the First Reformed Church of New Brunswick. 3) Seitje, baptized 21 Feb 1762 at the First Reformed Church of New Brunswick, NJ 4) Lemmetje, baptized 04 Apr 1765 at the First Reformed Church of New Brunswick, NJ 5) Jacob, baptized 27 Mar 1768 at the First Reormed Church of New Brunswick, NJ 6) Jane, born on 22 Apr 1773, based on her age on her tombstone.
Given the fact that George and Eva Boice's children are named as Jacob Boice Srs grandchildren, I think is certain that George, baptized in 1755 was the husband of Eva.
