this was a conversation I had with someone trying to help me with this part of the family tree
Mary Lynn William Eckley born abt 1796 in Philadelphia. Catherine Pontzler born abt. 1802 in Chester County, PA. There is a tree on ancestry that goes back further but I would try to communicate with the tree owner to see what her sources are for earlier information. Rebecca was Episcopalian so I think you need to look at church records for marriage, etc. Her husband
Mary Lynn Reuben was enumerated as Reuben Earnest in 1850, living with her parents. I believe because he was a wheelwright. He served in the Civil War, spent time in disabled soldier’s home in Virginia but was still with her in 1900 though the don’t appear in census together, they are in the city directories.
