Re: Charles Melson and Ann ? - ca. 1721-1766
Your first port of call for events pre 1837 in England should always be the IGI at www.familysearch.org
He was baptised, not born, on the date you show, parents John and Mary.
The marriage though doesn't appear on the IGI, which is far from complete, but is the best we have. Where did you get the date from? I'm surprised that you have the exact date but no bride's name. There are numerous parishes in the city of Lincoln - do you know which one the marriage took place in?
