I just found this thread, so I would like to go back to the first names thing.

We have two daughters: Mary Selena and Ruth Beatrice. Mary goes by Lena. It usually is not a problem except for the first few days of school when she has to train all the teachers, and at the doctor/dentist/pharmacy. Its up to me (and her) to remember which name is on her chart and offer all possibilities.

Ruth goes by RuBea (she does not capitalize the "b", but I do) which is pronounced like "Ruby". (Bea is a common nickname for Beatrice and actually was used by her great-grandmother for whom she was named). She also has to train teachers every year and finds it a little more tiresome. I can see her going back to Ruth as she gets older which would be fine with me. Ruth as a name was a bit much for an infant, but I think quite appropriate for a grown woman.

I have a little trouble with fancy name spellings - its just too cutesy, but I also have to be very careful what I say as I've done much the same thing.
