The Vail genealogy, 1947 states Margaret Allen was related to Ethan Ellen and he attended her wedding. But her father-in-law Micah Vail and Ethan Allen were close friends. many Allen families thought they were related to Ethan. I have been working on a Allen line in the area of Danby, Dorset and can not find parents of Margaret or her sister Lois or a connection to Allens from Dutchess Co., NY. My line is prob. related to Thomas Allen who m. Deborah Vail, sister of Edward.
