The document titled Profile of Richard Mills , shows what was found for him in the Sherington and Newport Pagnell area of Buckinghamshire and for his adult life in Enfield, Middlesex. His children are included as are some of his grandchildren. His will is also in the document.
It’s important to keep in mind that research on Richard was not intensive and no attempt was made to document every descendant or event in his life. It’s possible some of his children were christened or buried outside Enfield. He likely had children who moved away from Enfield and had their families in other parishes. Working with the surname Mills in the London area generates a lot of finds even in the 1600s, so other than the more obvious possibilities for Richard’s family no further attempt was made to follow this line any farther.
