I can't say I'm a big fan of any of them.
They don't fit together at all, imo.
I've never cared for
Priscilla. It seems like the third evil step sister to me. I'm not as against
Prisca, but still not a fan really.
Matilde is okay on its own. A little awkward in
America, but whatever. It's also the biggest outlier in the entire sibset.
Aaron and
Isaac go well together, but aren't anything special.
Joel seems kind of out of place all around, I think.
Copying Anneza...
Using the same initials, I'd have
Alasdair,
Ian,
Jasper,
Philippa, and
Mabel. (Or
Ambrose,
Indigo,
Joss,
Mona, and
Pearl.)
