Something that might help - I have picked up a marriage on Ancestry for them on the "England and Wales Civil Registration Marriage Index" - VOLUME 6D Page 11
Reg. Jan, Feb, Mar. 1918 at Kings Norton, Worcestershire.
Also a 1911 census entry, in Birmingham for Doreen - with her parents and siblings.
I have taken screen shots of them, if you PM me your email addres I can send them to you, don't think we're allowed to post them on here.
