There is a Lilian Seward, of the right sort of age to be Beatrice’s mother, in the Bristol area - birth reg Barton Regis Mar qtr 1880.
Puzzlingly though she looks likely to have married an Arthur Maidment in Bristol in 1902. So why might she be having an illegitimate Seward baby in 1903?
Hmmm. More work to be done.
This one is a red herring - see later post
