I too am a descendant of Simeon Amsden and Abigail Whitney. Joel Amsden Sr.'s brother, Lyman, is where my line follows. I have in my research that Lyman was born in Seneca, Ontario Co. NY in 1794. He married Cynthia Tibbets on April 1, 1816 in Ontario Co. and his son, Lyman Jr., was born in Ontario Co. So one might assume that Joel Sr. was born there also. There are lots of websites out there with the Amsden lines in them. Good Luck.
