Atalanta excursion to Riverstone

My sister Anne sent me the original of this photo, undated, which measures 10 cm by 5.5 cm:

Two arrows have been drawn with a ball-point pen: one to a tall thin man, the other to a young woman. On the back of the photo, someone has written: Mary Jane Kennedy (in sailor dress).

Mary Jane Kennedy [1888-1966], indicated by the second arrow, was my maternal grandmother, and the Kennedy family lived at Riverstone.

The Atalanta was a river-boat that operated on the Clarence. In the photo, it is berthed at Riverstone, Isaac Kennedy's property at Seelands, several miles upstream from Grafton. Since the boat is pointing downstream (to the right), it is no doubt about to leave, at the end of a summer day, for the return trip to Grafton. This photo was probably taken in 1909. I have the impression that Isaac Kennedy had organized a gathering at Riverstone for the family of Charles Walker, his former employee. I believe that some young Cranston men were also invited to the gathering. One plausible guess is that this was Mary Kennedy's 21st birthday party on August 31, 1909. Maybe the photographer was Charles Walker, Mary's future husband. I have attempted to identify some of the 26 people in the photo, but I am not sure that all my conclusions are correct.
