Updates:

Margaret and Chris Gravestock - we have located their birth sister and they
have been in contact with her. The family name of their sister was Wells and
not Gravestock so this was a particular challenge to their search.
Congratulations!
"Gil, you are the greatest, thank you so much for all your help in finding my
sister. We have so much in our lives that match."

On a personal note: I have just found a cousin that lives in the same area as I
do, his name is Tony Jefferson from Chatham, Ontario.

I have also a major lead on my birth father's family, through a distant cousin
Bruce Leeming from Guelph, Ontario.

Just recently found a distance cousin Anita Wills. A woman dedicated to the preservation of the black history of the underground railroad, and the native connections to her family.
