To conclude...

John Underwood senior marries Mary Saunders in 1805.
Their eldest known child John [Saunders] Underwood is baptised at Gretton in 1807.
He gets Ruth Crackstone into trouble and is forced to marry her in 1825.
John [Saunders] Underwood takes his family back to Yardley Hastings (I wonder if there is a removal order somewhere!) but Ruth dies less than three years later.
His parents have a family consisting apparently entirely of sons, so Mary Ann probably found a home with her paternal grandparents at such an early age that she never knew she had been born at Bozeat.
When John married Lucy, it was probably easier to start the marriage without the encumbrance of a four year old. I can't tell what happened between censuses, but I imagine Mary Ann never lived with her father for long.
She, like her mother, got into trouble, but the man did not marry her.
I wonder what her attitude to her own children was? George moved out of the area, and Elizabeth Jane, her daughter, was cast adrift by the deaths of two parents occurring so close together (nothing in the papers to indicate accident, epidemic or broken heart) and married very quickly afterwards.
