I adore [name_f]Leni[/name_f]! [name_f][/name_f] She’s currently on my list as a nn for [name_f]Eleanor[/name_f] but I suspect that’s too mainstream for you. [name_f][/name_f] What about:
[name_f][/name_f][name_f]Leonora[/name_f]
[name_f][/name_f][name_f]Gwendolen[/name_f]
[name_f][/name_f][name_f]Magdalen[/name_f]
[name_f][/name_f][name_f]Eleni[/name_f]
[name_f][/name_f][name_f]Briallen[/name_f]
[name_f][/name_f][name_f]Maialen[/name_f]
[name_f][/name_f][name_f]Eleonora[/name_f]
[name_f][/name_f][name_f]Leona[/name_f]
[name_f][/name_f][name_f]Leocadia[/name_f] (maybe with an N middle name?)
[name_f][/name_f][name_f]Lilwenn[/name_f]
[name_f][/name_f][name_f]Madeleine[/name_f] or [name_f]Madelaine[/name_f]
[name_f][/name_f][name_f]Evangeline[/name_f]
[name_f][/name_f][name_f]Emmeline[/name_f]
Good luck!
