My 1830 Greenup Co. census shows Lewis in the 20 to 29 age group with two children in the 0 to 4 age range. On thing I did find interesting is that Catey shows up in the 50 to 59 age range with three kids. Also just below Cateys name is Greenup and John. Being that close in the census I would bet these are some of Lewis's siblings. Hopes this helps.
