Hi Meg. My name is Stephen Smith and my mothers maiden name is Black. Alan Black is my 3r great grand uncle as I am descended from his brother Donald Black. I only have limited information of the PEI Blacks. Alan had Christine had 4 children (Catherine, John, Roderick and Mary). Of these, I know John settled in PEI and was married to Mary Steele. They had 2 children that I know of in PEI - Stephen (b:1866) and John (b:1868). That is the overview. Hope this helps. If you receive any more information I would love to see it.
