“Ursa” is Latin for “bear” — the constellations Ursa Major and Ursa Minor are called in English “Big Bear” and “Little Bear”. Ursula is the feminine form.
I liked the stories of Ursula Lehmann in Olomeinu, and there were some other Ursulas in my private life who impressed me with their middos. Also it sounds nice to my ears.
Now, did you explain “BSD” on any of these threads? Does it stand for BiSiyatta Dishmaya, is it your initials, or is there an even deeper meaning? (Don’t feel that you have to tell though, we’re just curious.)
