Thanks, Annie....no, it's OK. I've got more time than most people to hang around here & my posting might drive other people crazy, but it helps clear my mind (& it certainly needs that)
What you could do, if you've got

? hours spare (she said graciously) is to see if there's a baptism of a William Hudson to a John & Ann Hudson in Notts between 1800/1820, or a baptism of a Hudson baby in 1800 , parents John & Ann Hudson. That would probably rule those out as parents of my William.
Maybe Leicester Family History Society will come up trumps for both of us. My Hudsons certainly moved around. William....Shepshed to Ruddington to Loughborough, his son Ruddington to Nottingham to Derby & his son Derby & then through lots of Notts villages before settling in Nottm itself.....& they're only the places I know about.
As I've said, the worst family of agricultural labourers in the world
