Hi,I was just reading about Amity Twp. and I have a question. I am researching the Detrick's ,DeTurk's and Deithrich Family in Pa. I recently read that the DeTurk's came to Oley,Twp., Berks County In 1710 or 1711. If Berks county was apart of Philadelphia County until later in the 1700's,where is the best place to start searching? My gggrandfather was supposedly born in 1809 Lancaster County,but I am having trouble finding Detrick's in Lancaster county,but I have located them in Berks. Can someone help me out here? I am planning a trip to Pa.,in June Thanks, Susie
