I really enjoy just [name_f]Tali[/name_f] actually, and I agree that the spelling could be used for either pronunciation. [name_m]Tally[/name_m] reminds me of ‘tally marks’ – not a negative, but it feels a bit more modern and word-y than your usual style.
[name_f][/name_f]From your other options, I like [name_f]Talia[/name_f] and [name_f]Talitha[/name_f] for you especially. The pronunciation of [name_f]Thalia[/name_f] confuses me as well. I think the ‘th’ is pronounced in Greek if I remember correctly (a [name_m]Theodore[/name_m] vs. [name_m]Thomas[/name_m] situation)? Anyway, it seems like you don’t love it regardless so I would just strike it from your list.
[name_f][/name_f]Other full names: [name_f]Catalina[/name_f], Castalia, Talina, Talisia, [name_f]Abital[/name_f] / [name_f]Avital[/name_f], [name_f]Atalanta[/name_f], [name_f]Cataleya[/name_f], [name_f]Vitalia[/name_f]
