Richard Odom of LA and MS

I found Richard Odom on the 1820 St. Helena Parish, LA census, page 358. He was listed as Richard Odam with the following in his household: 1 male <10, 2 males 10-16, 1 male 16-18, 1 male >45, 3 females <10, 1 female 10-16, 2 females 16-26, 1 female >45. I am having trouble locating him on other census records. Can anyone give me information on his wife and children?
