Im loving Dot/Dottie today. I do love [name_f]Dorothy[/name_f] and would have no problem using it, however it doesnt quite fit with my sibset so am trying to brainstorm other ideas (though Im not a big fan of [name_f]Peridot[/name_f] for me)
Im am totally ok with stretchy nicknames, nicknames from 1st & middles. The more creative the better
[name_f]Dorothea[/name_f]
[name_f]Theodora[/name_f]
[name_f]Theodosia[/name_f]
[name_f]Eudora[/name_f]
[name_f]Odette[/name_f]!
Ooh I hadnt thought of that one!
[name_f]Donatella[/name_f] & [name_f]Dakota[/name_f] came to mind, or maybe something like [name_f]Delaney[/name_f] [name_f]Ottilie[/name_f] 
I think [name_f]Bardot[/name_f] would really suit your set. [name_f]Ardith[/name_f] would be great too though it takes some more imagination.
Other ideas:
[name_f]Adora[/name_f]
[name_f]Dolores[/name_f]
[name_f]Doris[/name_f]
[name_m]Cabot[/name_m]
[name_f]Clotilde[/name_f]
[name_f]Gwendolen[/name_f]
[name_f]Modesty[/name_f]
Rhodanthe
[name_f]Sidonie[/name_f]
[name_m]Talbot[/name_m]

Some very fancy name suggestions are Theodenanda Theodenanda [name_f]Callidora[/name_f] & [name_f]Caledonia[/name_f] - maybe with a T middle? I’m going to use [name_f]Tess[/name_f] as my filler T middle
