Re: what does the name tre mean?
The only Tre I can think of is short for Cornish names like Trevelysn and Trethowan - which are surnames sometimes used as first names.
Tre is Cornish for "homestead" or "settlement".
But somehow I don't think this is the Tre you have in mind.
Now, I wonder what would please her,
Charlotte, Julia, or Louisa?
Ann and Mary, they're too common;
Joan's too formal for a woman;
Jane's a prettier name beside;
But we had a Jane that died.
They would say, if 'twas Rebecca,
That she was a little Quaker.
