Dorthea Frolich (Fraily) was the wife of Johan Frolich who came to the U.S. and settled in Amity, Burks Co. PA. Dorthea was born in Germany in 1724 and died in PA in 1786. They were married in 1739. I have been able to trace Johan back four or five generations. but not knowing Dorthea's maiden name stops me dead in my tracks.I have not been able to find anything about her maiden name in Ancestry, and was hoping some one more skillful might have found some information that they would be willing to share with me.She was born in Dielkirchen, Germany.Any help would be appreciated. Frolich has many different spelling and in Southern Illinois it has changed to Frailey.The Frolich's had two sons and at least two daughters,most born in the U.S.
