James, Thanks for your reply.Nicholas' sister Sophia is my 4th gr-grandmother. She married John Hutchinson Harry in Lincoln County. I descend from her only living child, Marcus Lafayette Hope Harry.
I have found Nicholas to have 5 brothers and sisters, Nicholas being the eldest. His brothers were John M and Samuel. John M. became the first county commissioner of Cleveland County after it was formed from Lincoln. His picture hangs in the Cleveland Co. Museum. His 3 sister were, Sophia who married John H Harry, Eliza who married Gabriel Beaty and Nancy who married Grandison Vaughn. They were the children of John and Eleanor Tucker. I have not been able to find Eleanor maiden name and was trying to find the connection to Nicholas Iler. For the Eldest son to be named for Nicholas Iler there most be a connection I would think.
I also am courious about the Wilson estate in Penn. that Iler refers to in his will.
