Rare But Strong Welsh Names

We find out tomorrow if we are having twins or not, so we have been trying to decide on 2 names for each sex. We both have a strong Welsh/Irish background and would like to honor it. So, any thoughts on our name choices would be welcomed. The combinations are not 100%, so we are open to switching things around. I have already posted this in the other forum, so I apologize if you are reading this again…just trying to get all the feedback I can. Thanks!!

[name]Lysander[/name] (Lias for nn pronounced LIE-us ) [name]Liam[/name]
[name]Emrys[/name] [name]Rowan[/name]
[name]Everett[/name] [name]Audric[/name]
[name]Emmett[/name] Octavien

As you can see we are not a fan or really common names! Our last name is Petty by the way, if that helps.

I like [name]Lysander[/name] and [name]Emrys[/name]

What about [name]Lysander[/name] [name]Emrys[/name], [name]Emery[/name] Octavien or [name]Rowan[/name] [name]Everett[/name] for combinations?

[name]Lysander[/name], [name]Everett[/name] and [name]Emmett[/name] get my votes.
