Hello Andrea,
Of course excluding something is often as important as finding something, just to clear the field of possibilities.
So, this should help, with regard to the above family that I suggested.
1871
RG 10/ Piece 3104/Folio 29
Civil parish: Birmingham
County: Warwickshire
Registration district: Birmingham
Sub-registration district: St. Martin
transcribed as Byroner
Head: William Byron (?) (crossed out and then clearly written above as Bynner)
Wife: Annie
daughter: Maria 2
daughter: Catherine 9 months
Armed with this new information, I then found their children registered as born in Birmingham under the name of:
Bynner
Catherine Sep 1870
William Henry Dec 1872
Annie Theresa Jun 1875
George Sidney Dec 1880
except for Walter:
Bynnes
Walter John Sep 1878
MARRIAGE: Bynner Walter John in Jun 1903 in Kings Norton.
So, I think that you can now remove this family from your "folder of possibilities" as it were and safely chuck them in the dustbin.
So, that's good news, I think.
It certainly whittles the choices down.
Hope it helps you.
