I attempted to use a double name without a hyphen when I was married the first time, becoming Elizabeth Creith Zlatin, with "Creith Zlatin" as the surname. Everyone treated "Creith" as a middle name. Eventually I gave up and returned to "Creith". If I had hyphenated, I mighta got away with it. A friend of mine added her husband's name to her own, removed the space and left the capital letter - JonesWarrick. Worked for her.
