I am trying to research my family history but can not find much information on my GGG Grandfather, Donald Campbell from Cape Breton. He was born around 1805-1811 in Nova Scotia. He was married to a Margaret ? who was born in Scotland. They lived around Big Pond, Cape Breton. I have census data from 1871 & 1891. Children are listed as Michael, Cathrin, Flora, Mary J, Mary, Stephen, and Alexander. I am trying to find out more about his marriage as well as his parents (possibly John and Ann Campbell). If anyone has information regarding this family line I would love the help.
