I’d encourage all of you to visit or at least check out the Friend Family Assn of America. The museum and extensive library are based in Friendsville, MD. Ina Jenkins Hicks is available to help, and she is a great historian and genealogist. She is the person who proved that the early Western Md Friends descend from Colonial Swedes. Many regional families married into the Friends, and there are many materials about early families.
