You have some lovely names on your list
[name]Matilda[/name] - gorgeous, I have heard it used a few times here in the UK but not so much that it is too popular. A great little girl & grown up name
[name]Juliette[/name] - my favourite, classic, underused (here anyway) and beautiful
[name]Cora[/name] - not a name I had thought of but it is beautiful.
[name]Agatha[/name] - Pretty but not a name I would use given your other choices being so lovely
[name]Vivian[/name] - [name]Lovely[/name], another classic
[name]Minerva[/name] - This is a name of a big estate agency over here and just makes me think of that, I can’t associate it as a name but that is me I think. I haven’t heard it as a first name before.
[name]Louisa[/name] - Again, lovely (sorry, I like your list a lot so you are just getting a lot of lovelies :))
