Nathanial Smalley of Penn

I am looking for the parents of Nathanial Smalley born 1813
in Bethlemen, Washington Co., Penn. He was first married to Rachel
Smith by whom he had 5 children. She passed away in the late 1840s'.

He then married Mary Panter Lambert in 1850 and they had 2 or 3
Children. They moved to Ill. Then he moved to Iowa where he
ppassed away.

Any help would be greatly appreciated. I feel in limbo since
I can't connect with my earlier Smalley line. My line is thru
John Smalley. My brother took the DNA which proved it.

Thank You,
Margaret Smalley Parnell
