I love the names you have! They are unique you are right
In my extended family most of us [my cousins] have unique names.
And the same has gone on with all our kids.

I think if you are worried, keep them close and don't say anything.

I had DS2's name chosen when I was preg with #2.
Just before I fell preg with him a friend of mine named her son the same name.
But I still used it when DS2 was born, and it wasn't an issue at all.
We both loved the name, and didn't mind we both had a sone with it.
We're still friends 12 years later
