Horrocks Family Genealogy Forum
The info I have is that my Margaret Horrocks married a John Emmons and had a son, Ernest John Emmon bd Mar 7, 1877. dd Mar 6 1973. So, I am guessing at this point along the same lines as you, that my Margaret and your gggrandfather may be siblings. Mst of my family came thru Canada too and seem to be marrying people from neiboring towns. What area of Canada did your side of the family come through?
I also have a Florence Emmons, who is my paternal grandmother who was born in Sheridan, MI in 1902. Hmmmm.....
