Sister Sarah; or, what became of Sarah Bailey

On a sidequest of a sidequest of a sidequest, I discovered that Ancestry.com now has ship manifests of the New Orleans slave trade. Out of curiosity, I started tossing in names of people who I suspected had disappeared in that direction. Up popped "Sarah Bailey" in an 1845 manifest from Baltimore.

Douglass had a sister Sarah who disappeared from the record around 1832-ish. She was misidentified for a long time as Sarah O. Petit because Petit had addressed Douglass as "brother" in a letter decades later. Petit meant "brother" in either a larger, figurative sense, or in a fraternal order sense, but not a literal sense. When I researched Sarah O. Petit, years ago, her history indicated that she could not have been Sarah Bailey, daughter of Harriet Bailey and brother of Frederick Bailey who became Frederick Douglass.

The Sarah in this record comes from Baltimore and is four years older than Douglass's sister. Baltimore would have been the main port of exit, so that isn't any problem to believe. The age is another matter. Frederick wasn't sure about his own age and could date himself by events in Baltimore. He actually thought that he was a year older than his actual age for most of his life. Is a difference of four years believable for Sarah? Or would someone else have been estimating her age and got it wrong? After all, Anna Douglass's age fluctuated wildly in the census.

Hester Bailey below her could be the cousin Hester, but Aunt Hester was born in 1810 and the Hester in the manifest is fifteen years younger. That seems a stretch. -- Wait! There was a cousin Hester born around 1826! Perhaps that could be her?

In any case, this is an interesting coincidence.
