I believe John Mitchell Maitland was the second son of my gg grandfather. This belief is based on his name and birthplace. At www.familysearch.org I located a marriage record for John Mitchell Maitland to Georgeann Davidson 31 Dec 1874 New Kilpatrick Dunbarton Scotland. I found the same family on the 1881 Scottish Census with the following children: Daniel age 5, John age 3, and Jessie age 1. Also living in the household were 2 boarders, Peter Gilchrist and Alexander Bilsand.
If I am right, John Mitchell Maitland parents were James Maitland and Mary Mitchell. James' parents were Daniel Maitland and Jean Buchanan and Mary's parents were John Mitchell and Ann McDermit.
