This is an interesting one. I think William Champion PUDDY was christened in Burnham Aug 12th 1794 as the son of Sarah PUDDY by William CHAMPION. Although I have the fiche for these baptisms it is very difficult to read and there is something in the next line - It might be that he was about 9 years old.
It looks as if later William CHAMPION fathered a child by another woman because in Jan 1795 there is another christening of what looks like Charles s/o Ann HARVER? by Wm CHAMPION
A William CHAMPION married a Grace PUDDY in Burnham in 1797 So perhaps this was the same one?
