Hello Up untill now I haven't been able to find anything with the De Lamadeleine name (just Lamadeleine). My husband's grandfather came from Normandy, France. He was married to a German lady (name unknown) they had 6 sons and one daughter and settled in Upton ,Canada. This information came from my husband's Mother, since his father died very young ,in his early 30's he didn't knnow him at all. He was Henri De Lamadeleine, We don't know his grandfather's name.
