Thanks for the info Slowhands you may well have solved my mystery of Thomas Fisher and Emily White whose fathers on their marriage certificate of 1865 have different surnames ie. George Combes and Thomas Allaway.
I have found what may well be a bastardy order against a George Coombes in 1841 the birth year of Thomas Coombes .I cannot find a similar order for Thomas Allaway or an entry for a birth entry for Emily White/Allawy 1840-1841 however.
