Hi,
Just a quick update re Jane Bowen - I found a baptism for a Jane Bowen 1865 16/01/1865 with parents William and Elizabeth. Lydbury North, Shropshire. I think it's too late but as you say the marriage certs will hopefully state the Father.
I've also been pondering over the 1891 census with the elder sister to Jane, Elizabeth Bather aged 5 approx birth year 1886. There is only the mention of "Pollie" (possibly Mary Jane) in the letter to Alice from Jane and a son in law (no name) which made me think maybe Elizabeth died.
I think she would have mentioned her? I don't know.
I found, quite by chance a death only the transcription on Find my past of a Lizzie Owen last name Bathers, gender unknown, birth year 1886, age at death 12, death year 1898, Newport, Shropshire.
Massive coincidence that the second first name states Owen, I'm thinking Bowen?

?
BATHERS, LIZZIE OWEN 12

Anyway, you both given me much to think about I hope I can check in now and again on my progress

Kind regards
