My limited research shows that a David McWalters and Bridget Slattery of Foxhall, Co. Mayo had nine children that came to Oakland, CA around the turn of the century (last century!).Ella did marry William Coggin and lived in SF. They had two children. A Michael, b. 1873, married Anne Walsh on 6/6/1901 and may have gone "East".The youngest child, Anne, married Patrick Shally and they had five children.David McWalters married twice, his first wife died at age 36.There are still descendants in the Bay Area.I have a John born bet. Ella and Anne, 1884?, and nothing more.
