Good question! I’d consider names like
Stetson, Blaize,
Fisher,
Carson,
Cade,
Logan and
Tucker to be ‘ultra-masculine’, so mostly more modern English/American names with harsher sounds in them. I’d also consider some more classic names like
William,
Simon,
Richard and
Martin as more masculine, probably because they’ve been around as boys’ names for such a long time and are probably the first things that come to mind when I think of typical ‘boys names’. Now that I think about it, there seems to be less of a concept of ultra masculine names in comparison to ultra feminine. How interesting!
