Sophia probably married about 1826 - the first child born in 1828.
1850 Census. Dist 2, Union Co, Illinois, p.216, Hh 1006
Other Nortons counted on the same page in this 1850 census included Hiram, age 33, born in Indiana, and his family; and John Norton, age 64, b. TN with wife Mary, age 62, b. KY. I would think John & Mary Norton may have been Joseph's parents.
