I'd say look around, do some research, post some pictures and ask. I assume by names you mean trade names like "rasta" zoanthids? Sure you can make names up too, doubt anyone would care what you call it. Won't do you any good though.
sell some frags like the follow:
I don't know the lineage but its "what looks like a leng sy cap", "what looks like a Battle Corals tricolor Secale", "what looks like a polleti yellow tip"
etc. That way I'm not misleading on actual lineage, but they get the idea of what the coral looks like.
