In the 1850 census he was recorded with his brother Benjamin Seymour, although according to Bath Co. marriage records he was already married to Lucretia.

1850 census of Bath Co., Ky, division 2, enumerated 6 Aug, lists on p. 49 as family #335:
Benjamin S. Wright, 29, farmer; Martilla, 22; Clarissa, 3; Charles W., 3; Thomas, 20. All born in Kentucky.

Her death certificate records Lucretia Wright, age 93 years 7 days, born 5 June 1821 in Bass Co., Ky, died 13 June 1914 in Lee’s Summit, Jackson Co., Missouri, widowed, father Chas Clayton, born in N.C., mother’s maiden name Dolly Barnes, born in Ky, cause of death myocarditis, informant Virginia Shrout, Lee’s Summit, Mo, burial in Lee’s Summit.

I have not been able to find Lucretia or her daughter Melissa from her first marriage, to Samuel Crain, in the 1850 census. According to Bath Co., Ky marriage records, she had recently married her second husband Thomas Jefferson Wright, but he was recorded with his brother, without a wife or any stepchildren. (Three of the daughters of Lucretia and Samuel were living with their father.) Probably Lucretia and Melissa were temporarily with some relatives of hers during that month, but were not recorded either because the census taker visited on a day she was elsewhere, or because it was not considered her home.)
