Jocelyn would be my choice for a mn. As a fn, in my experience it always shortens to Jossie or
Joss, which I couldn't live with.
Rosalind is pleasant enough; I've got personal associations with it that aren't too encouraging, but of course one's own child would come complete with her own associations!
Roberta.
Josepha is just too out there. I mind
Josephine much less. But I think I'd shorten
Roberta to
Robin.
Yvette. Nicer than
Yvonne.
Lenore is just mangled.
Eleanor or
Elinor would be lovely.
To my mind, the only hope of improving
Abigail is to use
Gail. With that spelling, of course.
Gale is too weather-forecast, and
Gayle is the ln of a West Indian cricketer who is dazzlingly talented and spectacularly, piratically dishy but that's no reason to use his ln as a female (or any) fn.
I knew a
Suzanne Edwina whose mn honoured an
Edward. I really can't see the Edwarda or
Eduarda versions working in an Anglophone environment, but maybe as mns they might.
