Hi Jim - thank you VERY much for all that info. - which is really a great help and, I think, is the right Harry Langler. Thank you for the info. on locations - I have found difficulty with the local areas and what counties they are in!
The Leah Smith I found in 1901 shows her as born in Smethwick (alto' her birth cert. says 'Bacchus Road B'ham - maybe Smethwick area?) - so presumably this is where she met Harry.
Also Leah's sister's birth cert. shows she was born in Soho Road Handsworth/West Bromwich.
I haven't been able to find the Leah M Smith in Balsall Heath 1901 census that Pam refers to - but will keep trying as I need to ensure which is my Leah.
You obviously know the area - do you know of North Western Terrace Nuiton(?) Place, Handsworth? I have a photo post card of Leah and her sister (or it may be her two sisters) sent to her brother (my grandfather). Unfortunately although it was written it hasn't been stamped so I don't know the date. I imagine early 1900.
Thank you very much for all your help.
