I have more info on Emily Rosamond BARBER and Elizabeth Mary BARBER one of whom was the grandmother of Norma Larson GILBERTSON.
Elizabeth Mary BARBER m. 3 Sep 1865, Wallingford, CT, William BLACK. Children: Lester Woodford BLACK b. 1866 Emily Adaline (Addie) BLACK BERLET b. 1 Jul 1868 Robert Franklin BLACK b. 27 Aug 1870 Charles Francis (?) BLACK b. 18 Mar 1872 Helen Edith BLACK FINK b. 2 Jul 1879
Emily Rosamond BARBER m. 6 Aug 1861, Wallingford, CT, John Calvin MANSFIELD. Children: William Pomeroy MANSFIELD b. 1863 Robert Melville MANSFIELD b. 23 Nov 1866 John Sheriden MANSFIELD b. 31 Jul 1870 Mary MANSFIELD NORTON
Is any one of these children the parent of Norma? Also, my guess is that both families are from Wallingford, CT.
