How can you resist using
Myra? It's a gorgeous name that is ripe for revival. It's a clever nn for
Marion Elmira (if you choose). And most importantly it's a family name.
Hester and
Enid are fabulous. But given your family history, I'd bump
Myra /
Marion Elmira to the top of the list. It's funny, because whenever I think of
Hester several names also comes to mind and
Myra is one of them. It's meant to be. :-)
