It seems that if you live in Ontario (I only recently discovered that there were lots in Quebec where I grew up) and your name is Embury or your have one in the attic then you are cousins with a host of folk. I recently wrote a cute tune about this.
My mother's maiden name was Embury.Our family is descenant from Andreas to David (brother of Phil) to John E. to John (born in Sorel) to James V. to John D. to Russell (whose name I have) to mom and us...
I found siblings of James Valentine Embury in the 1852 census this past weekend - cool.
The Embury family seems to have been quite prolific!
