I am a direct descendent of this line also.Yes, Isaiah was born 29 Dec 1820, married Mary Price 8 March 1841, and died 22 June 1903.He is buried in Delphos, Ottawa Co, KS.His father was Jacob Adams, b. 30 Apr 1797, the son of Conrad Adams and Sarah Boone (daughter of Benjamin Boone II, uncle of Daniel Boone.) Jacob is buried in Elkader, Clayton Co, IA, next to his brother Samuel.Their father, Conrad Adams, died in 1801 in Northumberland Co, PA(now Columbia Co,PA).We do not know where he was from--the " stone wall " we all seem to have in genealogy.A family letter says he was a first cousin to Pres. John Adams, but so far, no lst cousin named Conrad has been found.We are following other leads. I have access to other dates, etc., but this much will suffice for now.Please e-mail me personally, and I can help you out with those.My line is through Isiah's son David Richard b. 11 Apr 1849.
