Far left is Sydney Tivey (3rd Generation) born 1923, then his Aunt Edith Baxter (nee Tivey) 2nd Generation, born 1893.
The old gent is William Tivey 1871-1971 and next to him is his Great grandson Christopher Tivey.
This photo was taken in Salford 1971 and was due to be published in a local newspaper as a tribute to William who was due to celebrate his 100th brithday shortly after. Unfortunately he didnt reach his 100th and the photo was never published.
