The other two people who are identified are Robert CHEEK (4th from right back row) and Baker Banks CARVOSSO (3rd from right back row).
It is possible that Alice Mary CARVOSSO is the lass far left of the 'girls' row!
The location is Belair - notice the charabanc in the background. The people most likely to be in this photo are descendants of John WILLIAMS and his wife Mary Ann (nee CORK).
If you think you may be able to identify anyone - please contact me.
