Hello Karenn,
No luck I'm afraid.I've got no North/Watts and I checked with someone else who has the Watts surname and no Norths there. I had a look on the 1851 Wiltshire census and see John North c1813 with a load of children, but no wife at home at the time of the census. Another thing to think about, my Gran had Davis in her christian names but I can't find anyone in the family with the name Davis.Someone told me they did that sort of thing, so maybe that's the case with you. I see a John North married a Mary Maggs Feb 1835 in Salisbury. Don't let me put you off Watts it's just my thinking. Anyway good luck.
Regards
Jim.
