I can't see any other information for Allen Barnes on a tree on Ancestry.
However, Ancestry do have Warwickshire records -
Baptism - St Peter, Coventry
8 January 1902 - Allen AND Edith Barnes, both born 7 July 1890 - children of Henry and Elizabeth Barnes of 45 Queen Street - occupation Weaver.
There is a death registration in Coventry in June quarter 1930 for Charlotte Barnes, aged 46.
I can see a marriage for Allen Barnes in Coventry Registration District 6d, page 1873 - September quarter 1944 to Rose D Bicknell.
Added: There was another baptism with Allen and Edith - Mary Ann born 15 March 1886.
Plus another multiple christening the following year - some of them were married by this time
