Joseph GRANT England is not one and the same person as plain old Joseph England who married Mary Reed. They are two different people.
WE DO NOT KNOW WHO JOSEPH GRANT ENGLAND'S WIFE IS: Joseph GRANT England's wife's name is unknown as she died before the 1850 census. And there is no marriage record that I know of. Whereas Joseph England wife's name is Mary Reed and their marriage record is filed in Hardin County KY (02 Sep 1797).
BOTH JOSEPH ENGLANDS ARE SHOWN IN THE 1850 CENSUS RECORDS: Joseph GRANT England (widower) is in 1850 Washington Co MO census in the household of his daughter Laura A. (England) Ruggles.
Joseph England who married Mary Reed is shown in the 1850 Callaway MO census. This census shows Joseph England, Mary (Reed), John C. & Riley J.
THEIR CHILDREN HAVE DIFFERENT NAMES: Joseph GRANT England left a will in Washington Co MO naming his five children. They are: John Maxwell A. England, Wiley J. England, Sterling T. Eathason England, Laura Linda England and Mary L. England. (See Richard Stark's post on this forum.)
Joseph England & Mary Reed's children are: William Logsdon, David, Joseph H., James Burton, John C., Riley Jackson, Nancy England, perhaps Elizabeth England and Benjamin England.
Please, let's all quit melding these two people together! It's obvious that they are not the same people.
