[Opinions] Re: Josephine?
I think it would be okay. I don't automatically assume that a Josephine was even named after a Joseph, and Joseph isn't even the first thing that comes to mind when I encounter Josephine. I think of people I've named Josephine first.
If someone I knew named a daughter Josephine, my guess would be that she named her child after a relative, not an ex, if she happened to have named the child after anyone at all.
