The daughter Ellen should be a son Allen.

Note that almost everyone here is younger than implied by the 1850 census - William by 3 years, Polly by 6, and Phillip and Abijah by 2 years. Delany is also two years younger than implied by his birth record, suggesting that the 1850 census is probably more accurate than this one. Mary J. and Allen may also be older than reported here.
