I suggest you contact Alan Day, he spoke to her in the course of compiling English International, my memory for dates is not perfect, so I do not want to quote a date.
I understood it was 15 to 18 group.
Bearing in mind someone will have ago at me, for quoting the wrong date, I reckon it was late seventies, she used to play in a group with her siblings[sisters I think]

I am not making anything up, I have suggested you contact Nic Carolan or Stephen Chambers.
Jack you are quite right I am the sole source on the net for saying she won anything.
