Hi
1. You should search the census lists and all other documents of Thomas and Grace.
2. Then you could search the same documents about their children and grandchildren.
3. Then you could search their entry at findagrave or their obituaries in the newspapers.
4. Obituaries often mention all children and siblings of the deceased person,
often with the names of wifes/husbands and the place where they lived.
For census lists and other documents look at familysearch.
For newspapers of New York look at Fulton History.
Regards
