Another name for John was DOHERTY OR DOCKERTY, John.1
John was deceased when his daughter, Martha, died in 1888. He was described then as a journeyman mason.
John married Agnes CARMICHAEL. (Agnes CARMICHAEL was born about 1785.)
The marriage of a John Docherty and an Agnes Wallace is recorded as having taken place on 4 June 1797 at Dumfries, Scotland. This may be Martha's parents. The only informant we have is her nephew who gave her parents' names for Martha's death certificate in 1888. 1
