John Mitchell,38 Roxburgh St of Mitchell & Balmer,Draper & Clothiers 16 Square,Kelso. Thomas Mitchell,United Pres Church treasurer. Thomas Mitchell of Kirk Yetholm,registered voter in Kelso. Dispensary,Roxburgh St Kelso,founded 1777.Perhaps your James was connected to it?Hope this helps,Amanda,Canada.
