FYI...I descend from the Judith Wroe/Mary Cook line, too. I have a big listing of Ely folks in my database that connect to Laynes etc, which are also on my father's side, as is Wroe and and Briggs. I failed to mention my Briggs are in Texas.
I don't have Mary Ely + Briggs, but do have 2 Mary Elys....and about 30 listed that are related to me.
Benjamin Ely m. Martha Patsy Bonaparte Layne and had Isaac Ely b. 1827 m. Julia Elliot.
I have a Susan Ely m. Thomas Alexander. She is sis to Mary Ely above.
I have a Stephen Decatur Ely b. 1838 m. Mary Edwards Leister. This Decatur name also appears in my Lawrence Line.
Adam Lawrence also went to California as did some of my Laynes.
