I may be able to help you. My ancestor John Wiley was born March 30, 1790 in Harford County, Md. to Matthew (b. 1751, d. 1840) and Rebekah Wiley. Matthew's father was David Wiley (d. 1784) of Chester County, PA. John had a total of ten children and three siblings. Unfortunately I only know about my direct line, but I hope this helps.
