Hi, good for you Caz, go get them girl. I had a look at my notes from my visit to Wiltshire Archives. The info I have re Maurice Goodman's marriage is as follows. "Goodman Maurice Hiller bach of St Benet Grace Church Street, London.
Butcher Avis, spin, 11th July 1779 Lic
John Butcher, Sarah Goodman."
I presume the Lic means license, which could suggest non conformist.
What is also interesting is that there was a Sloper John bach (the name bach again).
Plank Avis spin 31st May 1834
John Burden Ann Sloper.
I suppose as the name bach was written with a small b it may not have been a surname.
