Hmmm. Considering
Dolores is from the same root as the word "dolor" (= sadness), I wonder at this one. I know the first syllable is pronounced with a different vowel as "dolor" and the stress is on a different syllable. But as a namenerd I can't get past the "sadness" of it. I still have that problem with
Tristan ("triste" = sadness in French) even though I know the root for the name is probably something very different. A little bit of knowledge is a bad thing sometimes.
Besdies, that double "L" just looks so wrong in Dellor.
