I’m a male and going to legally change me name, both last and first name and not planning to get a middle name. I know I’m going to have my last name changed to “Chill” for sure. I’m looking for a first name associated with warm/ hot/ summer/ fire to sore of “balance out” the “coldness” in my last name. Any suggestion? I’ll prefer name with only two syllable and starts with letter “B, C, L or M” but all suggestions are welcome. Thank you.
Please try to make it unique and unusual.
I know a female (infant) [name]Ember[/name], but it feels more male to me. That would give you the fire association. Maybe [name]Ash[/name] (full name, no nn). [name]Ash[/name] might be to popular for you, though.
[name]Asher[/name] nn. [name]Ash[/name]
[name]August[/name] nn. Auggie or [name]Gus[/name]
[name]Ember[/name]

B / C / L / M:
[name]Bered[/name] nn. [name]Bear[/name] / [name]Blake[/name] / [name]Bradley[/name] / [name]Brando[/name]/ [name]Brandon[/name] /[name]Byron[/name]

Belenus - ‘shining’, Celtic sun god
Beltane - ‘bright fire’, Celtic festival
Bero - ‘hot’, Basque
[name]Blaze[/name] - Word name 
Borvo - ‘heat’, Celtic, byname for Belenus
[name]Brenton[/name] - ‘fire/flame+settlement/town’, nameberry says ‘town near the burnt land’
Canicus - ‘born of fire’, Latinized form of [name]Kenneth[/name]/Cináed
Conleth/[name]Conley[/name] - ‘purifying fire’, Irish Gaelic
[name]Leo[/name] - ‘lion’, Latin, I always associated lions with heat, summer and such
I couldn’t find any M names for you with fiery meaning. Personally, Borvo is a favourite of mine, with cool nickname [name]Bo[/name] ^^
Umm…[name]Pheonix[/name]?
