Also on our list is [name]Thea[/name] [name]Rosalie[/name].
i like [name]Shiloh[/name]
[name]Thea[/name] [name]Josephine[/name] is my favorite. 
[name]Tirza[/name] definitely gets on the list of the best names ever 
Now, on to her sister :
[name]Thea[/name] [name]Josephine[/name] - I love [name]Josephine[/name], and it fits well with your other children’s middle names.
[name]Thea[/name] [name]Susannah[/name] - I’m personally not as fond of this one.
[name]Thea[/name] [name]Clementine[/name] - I do like [name]Clementine[/name], but it’s becoming quite trendy - how about [name]Valentine[/name] or [name]Ondine[/name], instead?
[name]Thea[/name] [name]Juliet[/name] - I don’t think this has the best flow, but it is nice.
[name]Thea[/name] [name]Julianne[/name] - Pretty.
[name]Thea[/name] [name]Caroline[/name] - Flows well.
[name]Thea[/name] [name]Louisa[/name] - This also has a really nice flow, and is very pretty.
[name]Thea[/name] [name]Catherine[/name] - A little plain.
[name]Thea[/name] [name]Rosalie[/name] - While I love the name, for some reason I am not as fond of this one.
My favourites (in order) :
[name]Thea[/name] [name]Louisa[/name]
[name]Thea[/name] [name]Josephine[/name]
[name]Thea[/name] [name]Caroline[/name].
