Hi Charlotte
The birth address was given as Laburnum Cottage, Marsh St, Erdington and the mother's address at the time of registration was 1 Aylesford St, Leamington. The Arthur Day Lawrence named as father was down as 'Accountant', but the Arthur living nearby was actually a groom in 1901 working for a retired solicitor - bit of a gap in occupation there!!
If it was the Mercy from the Coventry Cross, her parents were still in Walsall (at least until 1901) and had been for many years.
I have followed loads of trails based on census info. (including the fact that there was an Edith L Marks staying as niece at the Coventry X, but that does see to be a co-incidence as her family were a wealthy London banking family that Joseph Lee, proprietor married into - I tracked them in every direction with no link obvious) but all seem to be red herrings, which is why I am desperately trying to pin down a marriage.
I have had a look-up done by the library in Leamington who tell me that the name of the occupant listed on the Electoral Roll in 1905 is a William Thomas Summerton. Of course, this could be the owner of the property rather than the occupant, but no link that I can find.
I am trying to go to Birmingham next week, but not really sure what I should be looking for - I am relatively new to this - or even there are records there which may help.
Any guidance would be very gratefully received
Regards
Tracy
