One of my sister-in-laws is EllaMarie but I'm always uncertain whether the "M" is capitalized or not. I'd prefer a two word name for her like yours Mary Alice, at least there isn't any doubt :-) I do have trouble with people who would see someone's name, Mary Alice Lastname and decide the person had stuck their middle name in there, just kind of arbitrarily! The person looking at the name wouldn't do it so why do they think the person who wrote or said their name did?
