Hi there,
thank-you so much for your help with this. I had a look at the address you found for the twin boys and the road which was given as their address on the 1901 and they are very close.
Would it be possible for someone to check the electoral register for 10 Wilson Street, Barnsley?
The odd thing I discovered was that almost all their children were conceived April-ish time and born the following January time! Poor Maggie didn't seem to get a minute's peace and was only un-pregnant for a few months after giving birth before she was pregnant again!! The twins birth doesn't overlap any other pregnancy she had but it's very close!
I also checked the website with all the memorial inscriptions, no luck

So, does anybody have access to the electoral register for 1902, Wilson Street, Barnsley and would they be a treasure and have a look to see if a Mr Alfred Lee is there?

I'd be so grateful and this family has been really difficult to research!!
Many thanks
Mandy
