Generations on the O'Brien and Lamon side

The photo below was received from cousin Mike O'Brien, showing my great-grandfather Harry O'Brien & sons Lowell and Harry Jr. and 2nd-great-grandfather Uriah Lamon and his sons Herman and Edwin Lamon. I'm not sure on the year of the photo, I'm guessing about 1923 as Henry Lamon was born in 1922 and looks to be about a year old in this picture.
