WFL says that Robert had two daughters by his second marriage, Mary and Eliza. The 1850 census clearly shows one daughter named Emily, and the 1855 census says Emiline. I’ve assumed that she isn’t an additional daughter, but that her name was transmitted incorrectly. Note that Robert had a daughter named Elizabeth by his first marriage.
