I try to find one that seems to fit my description of the character xD Basically, I either make one up myself, or scour online or the library for good enough names. I really like finding good names (( :
Naming characters is such a huge thing for me. I don't know why, but if a character's name doesn't sound right, I'll obsess over it forever haha. So this means I usually just spend hours lurking on some baby names website to find one that suits them. I find I usually like to go for obscure or archaic names to make the character more memorable and unique.
