I am a descendant ofthe Kers of Roxburgh, a Scottish border clan.
My great grandmother was Sarah Mary Kerr, born in Strathroy, Ontario. Her father was Richard Weld Kerr, son ofthe Rev. James Adams Ker, who was the son of Mark Weatherby Ker, who was the son of Rev. John Ker.
There is some sort of connection to the Dukedom of Roxburgh, but I would like to find out more if possible.
