I believe that the Mary E. Alexander, buried at the Brick Church Cemetery, north of Stockport, Morgan Co., Ohio, to be Mary Elizabeth Brabham Alexander, b. 02 DEC 1819, d. 09 JUL 1863. Wife of Richard Haney Alexander married 23 Feb 1841 in Loudoun Co., VA. Mother to 10 children: John Thomas, James W., Sarah Elizabeth “Betsy”, Mary Frances, Richard H., David Marion, Joseph N., Alta A., and twins George Washington and Thomas Jefferson.
