Lookin for information details for Joseph Martin, born Abt. 1763 in Chichester Delaware, married to Susanna Brown (daughter of William and Elizabeth Brown) in November 15th of 1781, had 7 sons according to quaker records; Mordecai (1783), Lazarus (1785), Joseph (1789), Susan (1791), Levi (1794), John (1796) and William (1799).
Need to confirm my patrilineal linkage to Joseph trough John Martin. I know John C Martin was my 3rd great grandfather, born in Pennsylvania Abt. 1796. The only match I have found for name, birth date and place is a single Joseph Martin family quaker record with all of his sons birth dates and marriage date, but that's it, this as far as I have achieved to get.
Thanks in advance for any help or clue you can share.
