I’m sorry that you’re still battling some feelings about Stella’s name. I truly believe she has a magnificient, luminous and enchanting name 
Your list for a third baby is beautiful! All the options are amazing. [name_f]My[/name_f] favorites are [name_f]Iris[/name_f], [name_m]Jasper[/name_m] and [name_m]Atlas[/name_m].
[name_f]Iris[/name_f] has a beautiful sound and a magical meaning, associated with hope and diverse stunning colors. [name_f]Iris[/name_f] is the goddess of the rainbow, the messenger to the gods. [name_f]Iris[/name_f] is also a sweet flower and the name of the coloured part of our eyes.
[name_m]Jasper[/name_m] is very distinct, charming and enigmatic. [name_m]Jasper[/name_m] is a very interesting mineral. I love Jasper’s meaning!
[name_m]Atlas[/name_m] has a wonderful meaning. [name_f]My[/name_f] first association is the book that collects maps, illustrations and graphs of different parts of the world. Because of that, I associate [name_m]Atlas[/name_m] with the world map and to me [name_m]Atlas[/name_m] grand meaning is “world”.
I also admire [name_f]Olive[/name_f], [name_f]Hazel[/name_f] and [name_m]Cedar[/name_m]. I believe they would be a great addition to your set despite not having such an impressive, strong meaning like [name_f]Flora[/name_f] or [name_f]Stella[/name_f]. They still have lovely meanings!
I obviously associate [name_f]Flora[/name_f] with flowers. However, at the same time, [name_f]Flora[/name_f] is the [name_m]Roman[/name_m] goddess of spring and, in biology, [name_f]Flora[/name_f] refers to all the plant life found in a particular region or time. For that reason, I understand if you want to eliminate the sames related to any plants, flowers, trees or fruits.
[name_f]Stella[/name_f] has a clearer meaning - star. Would you consider with other names related to the sky or universe? I would probably stay away from names meaning sun, because the sun is a star, but I believe others could work. I think [name_m]Cosmo[/name_m] would be great, for example! [name_m]Cosmo[/name_m] is also a flower name, so it would share a connection with [name_f]Flora[/name_f] and [name_f]Stella[/name_f].
