Cillian

Where Cillian comes from

Cillian hasn't made it into the dictionaries we draw on, and nobody well known enough for an encyclopedia has carried it yet — so for now its story is the one the SSA record tells. Names that spell a familiar sound a new way often live here for a while before anyone writes them down.
