Lester Brown's mother's name was Edith Ann Blackwood, b. 3 May 1872 in Pembroke, d/o William Stuart Douglas Blackwood and Emily Olive Wentworth. I have not been able to find Cora Fitch in the 1900 USC. She and Fred were married in St. Stephen, NB. It might be worth trying to get a copy of their marriage record, in case it might list her parents.
