fishona, there are some diminutive suffixes in english, but most are not applied to people.. there is, from the french,
et/ette.. lunchonette, (a small place to eat,) and in US english, (UK english as well, i think) the irish een, smithers (a mess, disorder, pieces) becomes smithereens (small peices) and een is used for names, even by Dickens, Pegeen (not Peggy) Maura, (Maureen), Colleen, etc..
een show up in teeny weeny, (very small)

there are also, still in use, but losing favor, word ending that indicate a female, Actor/Actress, Waiter/Waitress.
and finally there is the odd word, like Blond/blonde.
