Yes, my grandmothers are
Barica and Janica (+ her 3 sisters
Danica,
Katica and
Marica) and my mother is Štefica. I have to say in my generation the only -ica names I've seen are
Slavica and
Dragica and both of them were named after their grandmothers.
I've never seen Lajčo before, so I've been looking it up and there isn't any definite info on it (it seems to be a form of
Lajos/ Lajoš, but not sure).
