I love the name
Liam, it's not overused here either, here it's a very rare name.
I also like
Joseph, although people will proably be shortened to
Joey or Jamy (most J-names are nicknamed 'Jamy' here)
Joey en Jamy are the names that are overused around here, so here
Liam would be something different
I named one of my characters
Liam, I like the sound and meaning of the name.
