I have a Great Grandmother, Ellen Beckstead b. c1866 in Canada, d. cFeb1931. She was married 3 times, 1st Elbert Claughlin, 2nd Charles Averill, and finally to myG Grandfather Henry Charles Lucas. I believe she had a sister named Ida, and have an obit for her brother, John b. 20 Jul 1878 Parishville, NY, d.16 Apr 1950 Ogdensburg, NY. I have both of her parents born in English-speaking Canada, names Matthews Beckstead and Mamcy Barkley. I wonder if you would look these people up in the book you have? I thank you, in advance for your effort on my behalf.
