I’m looking to add some more familiar names with a vintage feel to my list. Names that go with [name_f]Rebecca[/name_f], [name_f]Genevieve[/name_f], [name_f]Felicity[/name_f], and [name_f]Sylvia[/name_f]. I’m a big fan of “old lady” names but my husband is much more particular about girls’ names and a lot of my vintage favorites are vetoed quickly! Some of the vetoed names are: [name_f]Clementine[/name_f], [name_f]Adelind[/name_f], [name_f]Mabel[/name_f], [name_f]Maxine[/name_f], [name_f]Aurelia[/name_f]. Nickname rich names are a plus! TIA!
[name_f]Margaret[/name_f] (great nickname potential - [name_f]Maggie[/name_f], [name_f]Molly[/name_f], [name_f]Margot[/name_f], [name_f]Daisy[/name_f], [name_f]Pearl[/name_f], [name_f]Etta[/name_f])
[name_f]Minerva[/name_f]
[name_f]Millicent[/name_f]
[name_f]Susannah[/name_f]

[name_f]Matilda[/name_f]
[name_f]Rosemary[/name_f]
[name_f]Phoebe[/name_f]
[name_f]Miriam[/name_f]
Margaret was my first thought – vintage/classic and nickname-rich, it fits your description quite well and definitely matches the style of names like [name_f]Rebecca[/name_f] and [name_f]Sylvia[/name_f].
