I don't -like-
Olalla, but it certainly draws the eye. It looks exotic and spunky.
Antonia is charming.
Susana is nice, although I find
Susannah altogether more elegant looking.
Amparo is oddball and awesome.
Adelita is okay.
Cecilia is nice.
I like
Antonio,
Demetrio and
Mateo, but they don't grab me.
The only ones on your list I really hate are
Blanca,
Pilar,
Santos and
Lorenzo - but that's just my taste. There's nothing -bad- about them, I just don't like them.
