Hi Suz
This is really good of you - as they say 2 heads are better than 1 - so we might yet find him.
Here's all the information I know about them - not that there's alot
When George and Maria married, Thomas was listed as the father and it doesn't say he was deceased so I have assumed he was still alive somewhere.
They married on 22nd March 1874 at the parish church of St Mary, Reading, Berkshire.
Someone has suggested also looking for the marriage banns in the parish as this might give a clue as to which parish they were from so I might also post on the Berkshire board see if anyone could look it up for me.
Thanks again
Pebs
