I saw your post and I thought I could help but only you would know if this is the person you need. I went back to www.geni.com and www.myheritage.com to see if I could find anything and I found this; Elizabeth Blackstone born 1775 married a Thomas Robinson Riley born 1785 -unk. Parents of Elizabeth are John Blackstone born 1758-1801 And Elizabeth Wise born 1758 -1830. Parents of Thomas are John Riley 1729-1785 and Ann Robinson Smith born 1750 - unk. I hope this helps but it is the only thing I found that was even close. If you need any more help please let me know, I will be glad to help if I can. Nancy
