I am searching for information on Margaret Dickey, b. ca. 1800 who m. 17 Mar. 1843, at Oxford, Chester Co. PA. to Thomas Powell of Penn Twp. Chester Co. PA. Thomas and Margaret Dickey Powell raised a niece of Margaret's, Margaret Francina/Elsina Dickey who m. Joseph GALLAGHER of Dauphintown, PA. 14 Nov. 1867. Joseph and Francina Gallagher lived in Chester Co. with her aunt after the marriage and until Thomas and her aunt Margaret' death in 1873. Can anyone identify these ladies? Thank you in advance, Mary A. Powell Sutphin in VA.
