Hi again! Apparently Ananias Allen was a favorite name of several Allen families, but I did find the following which may help you with the PA part of the family -
In Wayne Township, Lawrence County, PA
"History of Lawrence County, PA 1770-1877"
Ananias Allen started a grist mill at Wurtemburg @ 1800.
Wurtemburg was a German Settlement - one of the First Settlers was Ananias Allen1796-7Grist Mill called "Allen's Mill" where the first Presbyterian type Church met for their first meeting.
Also listed :
Jacob Allen in "Chew Township" first house in Lower Chewton.
Of course I can't say this is your PA side of the family, but it is interesting to read - I did see that there were others than German families in the various townships in Lawrence County , PA in the article.
But it might be worth looking into.
I used www.google.com "Advanced Search" and "Exact phrase" ANANIAS ALLEN - and scrolled down -
