My family research also contains the names McDonnell and Mc/MacDonald from Sand Point who worked in the lumber industry. Alexander Scott MacDonald who married Mary Hickey was born in the Alexandria area. His daughter Margaret Isabella known as Margaret or Maggie married Richard Dorion a culler for the Lumber Companies. Alexanders mother Ann married another McDonald in Alexandria area. She has half siblings as Margaret Scott married a 2nd time. She married Samuel McDonald and had 2 sons Duncan and James. Duncans birth certificate lists his name as a McDonnell who was born in Portage du Fort. Duncan married a Julia Ann Keyes and lived in Arnprior.
Samuels parents were a Donald McDonald/McDonnell who married a Sarah Kennedy. They lived in glengarry or Alexandria. Samuel had a brother named Duncan who had a son named Archibald who married a Catherine Mckinnon. I hope some of this is firstname.lastname@example.org
