What was the name of a small doll available in the 60s/70s – like Sindy and Barbie – only smaller!?

I found LOADS of clothes and small in my shoes faaar antique dolls that are too small to Sindys and Barbies – and I can not remember the name of the doll which they belong. The clothing style is very 60s/70s – and most of them have little yellow buttons. Can anyone help? It's driving me crazy!
