This is my list. DH and I can never decide on boy names! I have to have a list of names to present to DH. We just have very different tastes, ugh. My favorite name is Nathan but he doesn’t like it. Our favorite name was Liam but we just way way too many people who have used that name!! I have a Corianne nn Cori and a Taryn.
Out of those names, I like Dylan best. But I feel like your choices are much more common than your older children's names. I would look for something a touch more unusual to fit with the others. Maybe something like Alexander (Xander) or Lorn or Blaine or Torrence . . . I dunno, my style is quite different but I feel like if you searched for names similar to some of these you might find something that fits.
