William's father Philip Woodham appears in the 1803 Muster List in Milton Ernest as a labourer, no age given, married, 3 children under 10, class 4 ie married men over 30, married men 17-30 with more than 2 children under 10.
You need to check Ravensden parish register to see if the 1820 marriage entry gives parishes of residence other than Ravensden. As Rosie suggested on the Hunts board, you need to purchase the birth cert of one of post 1837 children to confirm the mother's maiden name.
There's an Elizabeth Woodham aged 66 buried in Stow Longa in 1849, although she seems too old to have had 3 daughters 1839-54. Perhaps her age at burial has been wrongly transcribed. In 1841 she's aged 40 ie 40 to 44 - to have had a daughter in 1844 means she was nearer 40 than 44.
All the children were baptised at Stow Longa, Hunts hence the other post
But we didn't know that until Rosie provided the link.
If you're posting what is essentially the same request on more than one board it's courteous to cross reference them for the reason Rosie gives. It also helps us to help you if you tell us what you know, rather than adopting the minimalist approach ie tell us to start with that all the children were baptised in Hunts
