Need Help to name Boy #3!

Hello! I am due I just 7 weeks and am having a terrible time deciding on boy 3’s name. My first 2 boys are [name_m]Anderson[/name_m] [name_m]Matthew[/name_m] and [name_m]Beckett[/name_m] [name_m]Thomas[/name_m]. I’m a teacher so a C name would fit right in. His middle name may be [name_m]Manning[/name_m] (family name). DH likes that for a 1St name but i worry he will be called [name_m]Manny[/name_m]. I like different names and we seem to have a last name for 1st name theme established. Our last name is one syllable and beings with M. Please help!

[name_u]Carter[/name_u]
[name_u]Carson[/name_u]
[name_m]Conrad[/name_m]
[name_m]Conan[/name_m]
[name_m]Connor[/name_m]
[name_m]Caleb[/name_m]

I think [name_m]Cyrus[/name_m] is a great name! (It’s my #1 name if one of my babies is a boy) [name_m]Cyrus[/name_m] [name_m]Manning[/name_m] is a strong name.

Other names:

[name_m]Calloway[/name_m]

[name_m]Christopher[/name_m] (also love this one for you!)
