You are just right with the identity of the ones you've mentioned.
As for the others: the guy between Pelham and Kemish, I thought he could be one of these three:
William Clark (40)
William Nutbean (30) -although he was 5' 9" tall, and our fellow doesn't really look that tall-
Albert Street (25)
Regarding the first one, I haven't found a picture of any firemen that resembles him. From all those firemen and trimmers who don't have a picture online, considering age and any other available data I'd dare to guess he could be any of these:
George Combes (34), John Hagan (35), Frederick Harris (39), James McGann (29), John Moore (29), Charles Othen (36), John Pearce (33)
My grandmother had a picture of him in 1912. I am quite sure. He was the brother of her father Joseph Pearce. Besides, I have that nose. Hahaha
I corrected the researches on his ancestry as they had the wrong John Pearce listed. My John was in the Channel Islands during the census periods they were looking at. This family had a long navel history. My grandmother passed in 2010. I saw the photos she had in 2008 and they were supposed to be passed onto me, sadly they weren't.
