Good to know. I didn't think to check the extended family. They're ok with repeating names if they're family names, but no proof on if they will repeat sibling names that aren't already honoring. So maybe they'll get to
Matthew if they run out. There's not that many more popular M names that aren't really similar to names they've already used.
If they have another, I'm thinking
Max (a bit much with the other M-k sounding names but that never stops them) or Miles/Milo before they use
Matthew.
