Personally, with my non-puritanical mindset, these names sound odd to me (except for
Mercy,
Phebe, and Tituba [Tituba, because I read “The Crucible” back in high school]). Though, I admire the thought that Puritans put into their children’s names; they all had a special meaning. Despite my banter, I really enjoy the sound of Bethiah! I think that Bethia (this spelling) would be a cool name, though I don’t know its origins.
