Hello Liz I was born and lived in Edinburgh until my marriage, so I know it quite well. However, in all my years of research, I have never come across a "Roxburgh Parish" or "Old Greyfriars". I wonder if Greyfriars was an actual street address? There was an Edinburgh Parish and a South Leith one. I will certainly search for William's birth entry - but don't be too hopeful, because it was long before compulsory registration, and if the family were not members of the established church, it is unlikely to be on the OPR. I will let you know either way after my visit to NRH. Best Wishes, Doreen.
