Hello there
I downloded a copy of Robert Roxby's wedding certificate Reg no 3289
18th July, 1864 at the Minister's Residence in Rutherglen
Robert Roxby Bachelor aged 27 born South Hetton? Durham, Engand engineer father John Roxby Surveyor mother Jane Roxby nee Rowell
Ellen Dunphy spinster aged 21 born Kilkenny Ireland
father Martin Dunphy mother Margaret Dunphy nee Phelan
now the witness's names are Hugh Cain and Elizabeth Elliott
So this information may help JT in determining a family link
regards Jenn
PS how many times do we tell folks to get the marriage certificate cause it usually contains the most information, and in this case it certainly did, the death certificate wasn't going to show his mother's maiden name
