I'm thinking about calling my baby Helen, but I'm not sure about possible nick names. Can you tell me what your (UK) gut reactions are to Nellie/Nelly (elephant?), Nell, Hen, Henny, Len (chalet school?), Lenny (55-year old male casino entertainer?), Elle...
I know Hattie is usually associated with Harriet or Henrietta, but would it be strange to use it for Helen?
Which nick do you think sounds most "old aristocracy", or too much so?
