I saw your post. In the event you haven't found what you are looking for yet, I have a copy of "Jardines of Atlantic Canada" which says Margaret died Oct. 30, 1914 in Sillarsville Quebec and is buried in Matapedia Cemetery in Que.
If you are a decendent, perhaps you know of Margaret's middle name? I am trying to establish Margaret's father's family tree. I think her middle name may be Crow or perhaps Cronn? I think this is the maiden name of Margaret's grandmother on her father's side. Any thoughts?
