My favourite is [name_f]Eliza[/name_f] or [name_f]Elsie[/name_f] (although I think [name_f]Elsa[/name_f] nn [name_f]Elsie[/name_f] would be better). If your surname is Peregreen, I would avoid anything overly cutesy like [name_f]Pixie[/name_f] or [name_f]Poppy[/name_f] for first names. Those two choices sound cartoonish. Obvious flower and colour names may prove too heavily descriptive with a last name that contains “green” as well. [name_f]Eliza[/name_f] [name_f]Willow[/name_f] would be my favourite combo.
I like [name_f]Elsie[/name_f] [name_f]Willow[/name_f] and [name_f]Eliza[/name_f] [name_f]Poppy[/name_f]. If you are looking for 3-name combos, I think you need to add some less nick-namey names to the list because a lot if them have similar endings.
