Oh gosh. I immediately think of the train system that they have in Atlanta. But I guess as long as you don't live near Atlanta (which I'm assuming you don't), then no one will have that association. Out of all those
Martha,
Marcia, etc names, my personal favorite is
Marthe. But I can see how people wouldn't find it appealing because it's pronounced the same as the word "mart" (in French anyway).
Wdyto...?
