Classification: Query Message Board URL: http://boards.ancestry.com/mbexec/msg/rw/UW.2ADI/1986 Message Board Post: My Mary O'Brien bn. May 1875 was probably boarding with someone in San Mateo County in 1910. She would have had a son, John, 12 years old and possibly other children. Can't find her because she wasn't Head of Household and I don't know who she lived with. I just know she didn't live with her husband, a merchant in SF. Can anyone help? TIA, Kris Mays
