I
LOVE LOVE LOVE Hannah. We named my daughter
Hannah back before the popularity boom of the late '90's/early 00's. I would not say it's 'trendy'. It's a biblical name which will stand the test of time. It just happened to get popular b/c it is so beautiful.
My favorite boy sib names for
Hannah are
Matthew,
Caleb or
Joshua.
Sister names would be
Leah,
Emma,
Elizabeth and
Abigail.
It's a great name, go for it!
