Hrm. It's an interesting name, but I don't particularly care for the "bohum" part of it. It reminds me of "bah humbug." I wasn't sure how to pronounce it, but I saw your comment on the name and, really, I think it's quite lovely. It sounds very exotic, but not
crazy exoctic. Boža is a cute nickname. I also like
Mila,
