Janet, Pam(ela) and
Roger go together well as 1930s names;
Cynthia is more ornate and seems more 60s.
The llamas have got very sweet names ... I'm guessing Bounty is white with a touch of chocolate brown?
I like
Pamela, nn
Pam,
Roger and
Jemima: we have no bad associations here in South
Africa, but it doesn't get used much at all.
