I named all my characters and gave each of them specific "retinue" units.
I have a quead of 'zekers called "The Rippers"
A squad of Chosen called "Fists of Korvellus" (korvellus being my armies Lt who always rolls withthem in
apoc games)
For normal units i tend to come up with a suitable name for the chapmion and name the squad that, similar to the way
SM squads are named.
I tend to name my vehicles more than my infantry anyway:
Land Raider "Tide of Wrath"
Land Raider "Bitter Legacy"
Shadowsword "Warp Hammer"
Brass Scorpion "Blood Glaive"
Dreadnought "Tridus"
Dreadnough "Deimos"
This sounds stpuid, but if you are looking for names with specific meaning try this baby names website:

you can type in a meaning or an ethnic origin and it will give a list of potential names. I used this to name all my characters and sergeants in my Crimson Fists army.
