Today, I met a little girl (7 or 8 years-old) named [name]Helen[/name], but she goes only by [name]Ellie[/name]. I thought this was an unusual nickname for [name]Helen[/name], as I’d never heard it before. But I think it’s a nice change from the popular [name]Eleanor[/name]/[name]Elinor[/name]. What do you think of it? And have you heard any nicknames you wouldn’t have thought of for any names?
My name is [name]Helen[/name], and for years in middle school I tried to get people to call me [name]Ellie[/name]. There aren’t really any nicknames for [name]Helen[/name], so I think I felt left out. 
I have a friend in her late 30s who is [name]Hellen[/name] nn [name]Ellie[/name].
I know a [name]Helena[/name] nn Hellie, and a lot of accents would drop the H anyway, so I think [name]Ellie[/name] works. Never heard it before, and also nice to see [name]Helen[/name] on a youngster.
Seems normal enough to me. [name]Nell[/name]/[name]Nellie[/name] is traditional and [name]Ellie[/name] is close to that.
