Hi Marty, I work with the early Pennsylvania Quaker families.
Do you have a known connection to the Tamar Allen-2763 line from Chester? Have you looked at the information from the Blackburn Family Association?
The Blackburn Family Association has John Allen (1756-1837) that married Amy Shepherd as desending from John Allen-1484 & Amy Cox-546
Lines as recorded by the Blackburn Family Association:
John Blackburn Jr.
> Margaret Blackburn
> > Amy Rebecca Shepherd & John Allen (1756-1837)
> > > Joseph Shepherd Allen (1783-1847)
> John & Amy (Cox) Allen
> > Joseph & Deborah (Hill) Allen
> > > John & Amy Rebecca (Shepherd) Allen
Does this look like the right family? I'm looking through the Quaker records and have these families associated with two meetings (so far). This information is from a few different places, I haven't gone to see what original documents are actually available.
1713 : Newark MM - John Allen accepted from Ireland
1719 : Newark MM - John Allen reported married to Amy Cox
1763 : Menallen MM - marriage of Solomon Shepherd & Margaret Blackburn
Then I got distracted creating the category for the Menallen Monthly Meeting. The Burial Ground at Menallen Friends Meeting is a National Park Service Underground Railroad Network to Freedom Site. The Blackburn family is associated with their early history. Interesting stuff.
I put some notes on Solomon Shepherd-2333 and I'm working through a few more links before dinner for connection back to John Allen.
