John Maddock, b.ca 1786, Clipston, Northamp., Eng

A previous query was posted, #261, and although I found my g-g-g-grands marriage to Elizabeth Perkins in 1813, information about John Maddock/Mattock/Madoc/Madox remains a mystery.His name is spelled both Madoc and Madox on their marriage certificate, and since early 1800s his heirs have all been Maddock.They had 8 children all born in and around Clipston.I would very much like to learn who John's parents were and his brothers and sisters.Am willing to share what information I have.
