I'm sorry about losing your grandfather. It's sweet of you to want to use his name for a child to honor him.
I'm glad you're starting to warm up to
Terence because I've always felt it was an overlooked gem of a name. It has both a dashing quality and an intellectual one which isn't easy in one name. I find it very attractive.
Terence sparkles. I can't think of any nn, though, other than Terror. ;-)
Terence Isaac,
Terence Daniel and
Terence Joseph are my favorites from your list. With the family significance of
Joseph, I'd say go with that one above the others. But just because I can't resist making combos, here's a few more to ponder:

Sorry for any repeats. Do you like any of these?
P.S. For a girl, how about
Kateri (for
Terry) or
Leonie (for
Lee)?
