I would just like to share the fact that I believe that I have proven that Edward May as well as his brother John was not in the May Brothers picture here: http://www.wikitree.com/photo/jpg/May-2828
Based on the faces of everyone in the picture not matching up enough and my discovery of half of a child's head (didn't fit in the image apparently) in the second version of the picture that I have not posted, I do not believe he is one of the four.
They are definitely all brothers as they have the same nose, mostly rounded headed James' head (far left) seems more square though and Patrick has a beard that obscures his features but they look like brothers so I could rule out any of their brothers-in-law, I believe.
Going back to the child's head in the unposted version, I believe it belongs to my granduncle, James S May III who was born in 1926 and appears to be no younger than 4/5 so I believe at the earliest the picture was from 1930 and in 1940 at the latest however, I have no proof of the end time-frame.
Either way, I am fairly certain about the time frame so that takes care of identifying 4 of the 8 possible brothers who could have been in the picture: James and Patrick are in it while John and Edward died before it was taken, 1915 and 1923, respectively. I have a feeling that one of them is Michael May who was the last brother to die, to my knowledge. He died in 1963.
One of them could also be Joseph May who I will make a post about in a second.
Have a good day,
