Hi Everybody,
Just to expand upon the point I made, I suspect my grandmother, on my father's side was illegitimate, as her marriage certificate, does not give her father's name. Her mother's surname was Wattie and my father was given this as his middle name, so he was Thomas Wattie Allan.
I have not delved too far into this, for reasons of delicacy, but my great grandmother, Jane Wattie was in domestic service, in London, when my grandmother was born and putting two and two together, I would postulate that the father may have been connected to the family that she was working for, or have I been watching too much of "Upstairs Downstairs".
Best wishes,
Dave
