Ptolomea [name_f][/name_f]- oh, she sounds so dreamy! Much more ethereal cloud than fiery underworld 
I’m not helping you let go perhaps, because I really want to suggest a spelling change to Talomea or some such? (Tolomea is listed as a submitted name on BtN [name_f][/name_f]- Italian fem form of Tolomeo.)
[name_f][/name_f]Some similar sounding name ideas:
[name_f][/name_f][name_f]Salomea[/name_f] (Solomiya is a Ukrainian variant of [name_f]Salome[/name_f], but I can’t find a PN guide for her.)
[name_f][/name_f]Tahmina
[name_f][/name_f][name_f]Alodia[/name_f]
[name_f][/name_f][name_f]Paloma[/name_f]
[name_f][/name_f]Shall we invent Palomea?
[name_f][/name_f][name_f]Haumea[/name_f]
[name_f][/name_f]TÃmea
[name_f][/name_f][name_f]Euphemia[/name_f]
[name_f][/name_f][name_f]Lamorna[/name_f]
[name_f][/name_f]Thalma
[name_f][/name_f][name_f]Tulia[/name_f]
[name_f][/name_f]Theolene, Théoline
[name_f][/name_f][name_f]Teodora[/name_f]
I’ll also have a hunt through my hearted name list here on NB and see if there’s anything Ptolomea-like I can share.
