Looking for Robert Mollett of Smithfield S Marriage to Elizabeth

I have various deadends, but one of current interest is the surname of Robert Mollett's first wife. Robert was a pastrycook and was born in Norwich, but his children (John, Robert and William) to Elizabeth were all born around Smithfield in London. He lived for many years on Skinner St. The marriage would have been around 1804. I am descended from John.

Thanks,
