Laurel Kathleen is very pretty and I like that
Kathleen would honor the grandmother.
Re:
Judith Veronica, each name is quite strong so I don't really care for them paired together.
Judith Miriam (or something equally balanced such as
Judith Naomi) would work better, imo.
Between
Miriam Helen and
Liora Helen I prefer the former simply because it flows a bit easier for me. In other words, the transition from
Miriam to
Helen is nicer than the one from
Liora to
Helen (at least it is to me, anyway).
Have you considered incorporating Sojourner into one of your female combos? Now *that* is a cool name.
