Hi..My interest in the names you mentioned is really that of JOHN PICKEN, and the 'Dunlop' part of Isabella's name as it is unusual and I am searching for information regarding the family of WILLIAM Dunlop PICKEN b. 23 Dec 1909 in Calgary, Alberta. He died 13 Jun 1966 in Vancouver, BC.
His father was HUGH PICKEN who was from Scotland and
I believe his mother was named AGNES. They are all part of my family tree which has taken me to searches in Scotland, Canada and Australia so far. I am in England, UK. Regards, Doreen
