In the 1850 Census, all 9 in the Liberty, Clay Missouri household have the same surname, so they may very well all be related. TR Dale 46y and Susan B. 38y are likely to be married an parents of most of the others. The parents and E. E. Dale 18y were all born in KY. The others including Alfred Dale were all born in MO.
T. R. Dale who is in MO in 1850 could well be Timothy R. Dale who married Susan D. Edwards 24 Jan 1832 in Shelby, KY. It's not uncommon for a middle initial to be different from one census to another, so Susan B. in MO in 1850 could easily be Susan D. in KY in 1832. Legability depends on the handwriting of the census taker and how the reader of the handwriting interprets what he sees.
