As much as I'd like this to be a topic where anyone can get pronunciation, etc. for a roleplay character's name, I realize it'll be mostly me asking for the help. I'll start us off by asking for help with stress (guesses bold) and soundings out (parenthetical question mark) of the Domitia (dau-mih-tih-a) family from a roleplay involving the revival of ancient Rome.
Handy pronunciation key noting that the long "a" is "ah" to avoid confusing it with the short "a" and the long "o" is "oh" rather than "o" so it's not confused with the long "u"s "oo" elaboration.
My character: (praenomen) Gnaea = guh-neye-a(?); (individual cognomen) Iuventās = yuh-vehn-tahs(?);
Sister: (praenomen) Līvia = lee-vih-a; (individual cognomen) Albīna = al-bee-na(?);

Dad: (praenomen) Marcus = mar-kuhs; (individual cognomen) Būteō = boo-teh-oh;
Aunt: (praenomen) Gāia = gah-ih-a; (individual cognomen) Lānāta = lah-nah-ta;
Uncle: (praenomen) Trāiānus = trah-yah-nuhs(?); (individual cognomen) Aselliō = a-sehl-lih-oh(?);
Cousin 1: (praenomen) Tiberia = tih-beh-rih-a; (individual cognomen) Flacca = flak-ka(?); and
Cousin 2: (praenomen) Appia = a-pih-a; (individual cognomen) Crīspa = kree-spa
