Hi, I know of the Togneris, Mr Roberto Togneri was a lovely man and a respected teacher and has very recently passed away, being in his 80s. My brother is friends with his son. He lived in Stirling. Don't know anything of his background, would be reluctant to post anything due to his children being very much alive. However, you may be able find an obituary for Mr Togneri and take it from there.
Cheers, Auntiemomo
