I am the great grandson of Thomas Murdock, born 1829, and Janet Murdoch, born 1821, but that is where my search backwards ends. Their daughter Ella Murdoch was my grandmother. I too, have one of those long stories.
I do know that Thomas' father was born in Nova Scotia and that his mother was from Ireland. And, that both of Janet's parents were from Scotland, but that's it.
