According to Rootsweb he was born circa 1747 in either Baltimore County or AnneArundel County, MD, and died in 1805 in Baltimore County.
There is little evidence that *this* Shadrack (Shadrach) Penn ever ventured far from Baltimore County, MD. He seems to have been mashed up with a cousin, Shadrach Penn (of Benjamin and Dinah), who was an early settler of Frankin County, KY.
Whether he had the wife/wives and child/ren listed here is strongly open to doubt.
I am a grandson here in Ohio. Just looking for help Shadrack is in my family Bible Look for anything on Shadrack Penn Thanks Larry lwpenn@webtooling.com
