This is a very old post, but I will toss out what I have.
A Rachael Perkins in my family married a Larkin Steele. It could also be Steel. They married in Sumter in 1833, so the timing is about right.
I cant find Rachael or Larkin in any census, the marriage record is all I find.
I can tell you some of the siblings of Rachael ended up in Anderson, Angelina, Robertson, and Leon Counties in Texas.
