MMorris,
I know it's been a while since you posted. Sometimes I scroll the old posts looking for info that may help me with my search.
I found a Webster familiy living as FPOC in the District of Columbia in 1850.

Anabella Webster 32 f b
Daniel Webster 18 m b servant
Cordelia Webster 15 f b
Wm Webster 12 m b
Issac Webster 6 m b
Julia Webster 10 f b
Charles Webster 4 m b

Hope this helps.
