I like
Erica much better than
Eric. And I was at school with a wonderful
Erica who died too young, a long time ago. So it's got positive associations for me.
I like
Heather too, probably better than
Erica (because I've got no personal feelings about it) but not much.
Heather was probably a bit more popular at one time than
Erica ever was, but not enough to affect people's views.
If you Google
Erica South
Africa you'll find some lovely pictures of our
Erica flowers!
