Hi Sharon,
Yes please, any info would be helpful. No connection I know of with Brownhills (this is in the 'Black Country near Birmingham), but Wisbech is a place that rings a bell.
They were in/around Boston, Lincs for many years, and got married in Spalding Registry office, with both giving addresses in Spalding. (5 High Street, in her case) Sylvester is '21 years' in 1922. Both her and Walter's father are down as 'General Dealers'. Walter's address was 'Commercial Road, Spalding'
I will need to check her death entry, but I think she was in her 80's when she died (1982). She could have been younger and just saying she was 21, so the 1904 birth entry is a possibility, but I will need to check the age at death first.
The Harris entry in 1904 is the only one that comes up on Free bmd, but I think I will need to check in more detail. (needs a trip to the library) Must admit I'm a bit at sea here, as I'm used to using place as a way to narrow down the correct family.
For me the places 'Wyberton, Wisbech, Spalding, Boston' were all places my mum talked of.
I will need to do some more digging and see if I can come up with more info on my Great Grandmother (mother to Sylvester), need to look at some of the pictures and see if there's a name, and also a death entry in the 1960's which might help. (I know she died between the mid 60s and early 70's).
Sorry I can't give you any thing else as yet....
Cindy
