I'm thrilled to have found this topic. The name change from Lamagdeleine (Ladouceur) to McDonald confused me for years.
As far as I've been able to determine, my great-great-grandparents were Francois and Marie Lama(g)deleine-Ladouceur, who became Frank and Mary McDonald. Their daughter Florestine (or Florence) Ladouceur married Peter Kelty in 1888, in Russell County. They had three children, two of whom were Edith and Edward.
I tried for years without success to find out more about Francois Lama(g)deleine and his wife Marie (maiden name unknown).
Does anyone here have these two people in their files at all?
I'd also like to know more - if possible - about Florestine and Peter, and their child Edith.
