You are right about the main branch of the Strettel/Strettle tree. I have problems with the Dublin branch because of the same names in multiple families of the same generation. My husbands ancestor (George) married(about 1712) a Strettle (Ann/Anne) in Dublin are trying to trace their children and their immigrations to "the colonies" in the mid 1700's. The Strettles are a wonderful family to trace and I have enjoyed learning about the Quaker merchant class in Dublin and Philadelphia. One of their descendants was mayor of colonial Philadelphia. They had vast land holdings in New Jersey and Pennsylvania.
Please keep me in the loop on the Strettle searches. Thanks Jana Rooke
