Everett John - I'll be honest, I'm not a huge fan of Everett although I do like both parts (Ever and Rhett) seperately, which is weird. John is very handsome and classical, although it doesn't really go with Archie's middle name. This is a very strong feeling combo though, and I do like Archer and Everett as siblings; Archie and Rhett <3
Levi Connor / Roman Connor - I love Roman Connor, I think it suits you so well, and I think Archer and Roman is such a handsome sibset! Levi is nice, and I can see it as Archie's brother, but I much prefer Roman Connor as a combo. Roman Levi Connor would be handsome too, and it fits with the two mn thing
Brody Charles / Brody Gideon - I like Brody, but I feel like with Charles and Gideon it fits better as a middle name; Charles Brody is very handsome (as is Archie and Charlie <3), and Gideon Brody is equally as handsome. Out of these combos I much prefer Brody Charles, the flow is better for me, although I do love Gideon.
Odin Theodore (GP) - I'm not a fan of Odin, but I love Theodore. This is a cute GP though
Gavin _____ - I don't like Gavin, it rubs me the wrong way for some reason. It is strong sounding though. Gavin Theodore would be handsome <3
Hmm, some boys names that I think sound strong are:
Sorry for any repeats, and I hope this helps some, Remy <3
