Many thanks to both of you for your replies.
I did think that sindaco was either the Mayor or the President/Chairperson who opened a meeting and I think the following quote is the correct meaning
|Decurion is a word with several meanings, but in your case this might be what you are looking for..... Decurion....member of the city senate, mostly made up of wealthy middle class citizens of a town society. They were responsible for public contracts, religeous rites & entertainment. They also supervised tax collection|
It does cause problems when you isolate a word and look it up in a dictionary guess it does need to be in context with the whole document.
Many many thanks for your help.
Now I'm hoping there will be some personal information kept somewhere about those people who 'sat on the board' all those years ago.
Hope the old saying is true that 'when a door closes a window opens.
