The only plausable candidate among these is the Thomas born 27 Jun 1799 if we assume that the mother of the children was Rispey Irish. One could imagine that they had several older children who had already left home by 1850, and that Rispey, who is listed a born in 1800, died in childbirth of Angeline; she would have been about 45 years old. However, there are some difficulties: Betsy (Elizabeth?) Cornell is listed as being born in 1802 which conflicts with the census record which would have her born 1811-2 (this level of inconsistency is unfortunately common) and the names are just Thomas, not "Thomas B.".
