I traced my family back to Henry Acton, who was born in Shropshire in 1671 and died in Maryland in 1742. His wife was Ann Penn, born in Shropshire in 1682 and died in Maryland in 1737. Ann's father is listed as William Penn who was born in England in 1640 and died in Maryland in 1696.
I don't see how this William Penn can be the founder William Penn, even though they lived during the same time period. Does anyone have any information about a William Penn associated with Shropshire? I've hit a dead end with this line.
