I'm also a descendant of the Rogers clan from Saratoga. I have some information to share with you. Perhaps if enough of us contribute pieces to the puzzle, we'll all one day solve it.
This reply will focus only on the Benjamin Rogers'. (Please see my other reply on Philip Rogers.)
There are two Benjamin Rogers in the Saratoga area, and they are father/son. The "Fish Creek" Ben is the son of Benjamin Sr. Benjamin Sr's wife's name was Mary, but I am not sure of the surname. It may be Kuntz, based on other replies I have read on this forum.
Ben Sr and Mary had twelve children - Benjamin Jr., Jeremiah, Caleb, John, Isaac, Joel, Sarah, Geramina, Mary, Margaret, Phebe and Elizabeth. Ben Jr was born 23 Feb 1765. I don't have birthdates for any of the other children. I do have a little marriage information: Sarah married a Potter, Geramina married a Swartwaut, Mary married a Wiggins, Margaret married a Smith, and Phebe married a Wilcox. I believe Ben Jr's wife's name was Jane.
The source of the above information is a transcribed copy of the will of Benjamin Rogers Sr. I can provide you with a copy of this separately, if you are interested.
I'm very much interested in Ben Jr, because I believe that one of his children was my ggg-gf Daniel Howard Rogers. Daniel was one of seven brothers who all migrated to the Litchfield area of Bradford County, PA. His eldest brother was John Rogers, born in Saratoga in 1782. Daniel was born in 1798. I believe his other brothers names were Platt, Nathaniel, James, Hiram and Martin.
I'd appreciate any information that you may have on either of the Ben Rogers and their families.
