[name]Dinah[/name] is very pretty!
I think the concern is valid, but coming from someone who grew up in a very [name]Christian[/name] home (and who is still quite devout in her beliefs), I don’t think it’ll really be a big deal. When I was young and learning the Bible stories, all I ever really knew about [name]Dinah[/name] was that she was [name]Joseph[/name]'s sister. And I always thought [name]Joseph[/name] was cool, so I thought [name]Dinah[/name] was cool by default, haha. By the time I was old enough to read the story for myself and discover how sad the story was, I still thought [name]Dinah[/name] was a cool person. Lots of people have negative associations to their names (I was named after my uncle, for crying out loud! Being given a traditionally masculine family name, despite its popularity on girls now, confused me a little in the head, haha.)–negative meanings, associations to not-so-great stories… sure, it is nice to have everything be rosy regarding a name, but if the meaning is negative (like [name]Marie[/name], which means “bitter”, and is positively rampant), or it has a negative story surrounding it (like [name]Dinah[/name]), I don’t really think it’s the end of the world. Sure, it’s a bit disappointing, but kids get over it.
If you don’t absolutely love it, then, yes, I would continue looking for a name with a nicer story attached, but if you don’t, I don’t think it’s the end of the world. Besides, from what I understand, [name]Dinah[/name] was a good girl–it’s just what happened to her wasn’t so great.
