Yes, Mary!I believe Seloa Middleton is really named Sylvia Middleton -- that the census taker just wrote it down scribbling it as Selma or Selva and everyone has been reading it as Seloa.That one letter is not clear on the one census.
Sylvia must have married a man with the surname of Nash because she has two sons of that name.
It is exciting!
Mary -- May your be flooded in your own search soon, too!:-)
