Lilian Maud Wood (1904–2000) my grandmother birth 30 NOV 1904 • Merthyr Tydfil

Are you sure she was born in Merthyr? I don't see a birth registration there.

I was also surprised, given they seem to live in the outer London area between their marriage and WW2 (electoral rolls on Ancestry), I can't see any birth registrations for children for this couple in that area.
