I asked my mom and dad, and they gave me two different answers. My mom is much more American than my dad is (they both have citizenship, but dad spent most of his life in Brazil and
Europe). My mom generally calls my brothers and I Americanized approximations of our names, so she said twins would be
Caitlin and
Bridget. Whereas my dad said a twin for me,
Catalina, might have been
Federica or
Vicente.
