The only one I would really have to avoid is
Susan. For whatever reason, and I've known an assortment of Susans, I just don't get the attraction. I love
Suzanne, and might consider
Susannah as a mn for family reasons, but
Susan itself is a no-no.
Helen delights me! Light and dancing and warm and open. From what little I know, it seems less liked in the US than
Ellen, which I find dowdy and pedestrian.
Margaret is a joy. Timeless, austere but radiant, the only issue is the nn question. I don't enjoy
Maggie;
Meg does nothing for me and
Megan does less;
Peggy is cheerful and bouncy but doesn't seem to work any more. And here in South
Africa the standard short form of
Margaret is
Margie, with a g rather than a j, and I can't stand it.
Deborah, like
Margaret, has a nn problem. The name itself is fine: good rhythm, good sound, good history, and who wouldn't enjoy sharing a name with a tough old lady who sat under a tree and judged
Israel? But
Debby ... is quite a powerful deterrent.
Deb is fine, but Debs isn't. Complicated name.
