I just started my research on the Tock family when I read your post. I believe the Mrs. FM Byers you are referring to is my ggrandmother, Mary Agnes Tock (1884-1971). She married Frank Mathew Byers in 1907 and they had one child, Dorothy (b1914), my grandmother. My grandmother is an only child and sadly she lost most of her family pictures when she moved many years ago. I would love to have a copy of some pictures if you would be so kind as to e-mail them to me. I would be so greatful!! I would love to be able to share any info I have! Thank you so much!
