I was hoping to find more variations for the [name]Lily[/name] names than [name]Lilian[/name]. Anything… even things that don’t begin with [name]Lily[/name] but have it in there. I am liking Tigerlily but I don’t think I could use that on a real baby.
I love [name]Lily[/name] names! My favorite, atm, is [name]Liliana[/name], but I have a serious thing for [name]Lillian[/name] and [name]Lilia[/name], as well, and can never seem to be able to decide between the three. I think [name]Lilibet[/name] is adorable, too, but I’m not sure how usable it is.
The only other idea I had would be [name]Susanna/name/[name]Zuzanna[/name]/[name]Susana[/name], which means “lily”. I think you could still use the nn [name]Lily[/name] for it. 
Or maybe something like [name]Delilah[/name]/Elila/[name]Alila[/name]? They don’t really have the “lily” sound–more the “lie” and “lee” sounds in the middle, but since the “lil” part is there, I think you could still use [name]Lily[/name].
I have to admit, Tigerlily is a guilty pleasure name.
other ideas:
[name]Lilianne[/name] ([name]Lily[/name]-[name]Anne[/name])
[name]Liliana[/name] or [name]Lilianna[/name] or [name]Lillianna[/name] or [name]Lilliana[/name]
[name]Lily[/name]-[name]Belle[/name] (there could be different ways of spelling this. I know a [name]Lily[/name] who gets called [name]Lily[/name] [name]Belle[/name] just as a pet name, but I really like it.)
[name]Lilith[/name]
[name]Lila[/name]
[name]Lilibeth[/name]
[name]Susannah[/name], [name]Susanna[/name], [name]Susan[/name], [name]Suzanne[/name], [name]Suzette[/name], etc. all mean lily (could be a formal name with nickname [name]Lily[/name])
[name]Lilias[/name] or [name]Lileas[/name] (Scottish)
[name]Lilium[/name] (Latin word for lily)
[name]Calla[/name] (type of [name]Lily[/name])
Azucena (Arabic)
Gelilya (Hebrew name); meaning = rolling hills
Lilyth
[name]Lilyana[/name]
I’ve always been very fond of the Hebrew name Analillia. It’s a join of [name_f]Ana[/name_f], meaning Favoured [name_f]Grace[/name_f] and [name_f]Lillia[/name_f], for the [name_f]Lily[/name_f] flower
