The man on the bottom row, far left is Walter Leigh White (went by Leigh), and I can confirm that he was based in Douglas, AZ in 1917. I'm curious to find out if Leigh and Thomas were related (cousins, possibly) or if the common last name is a coincidence. Leigh's family is from Missouri, New Orleans, and originally Virginia before the Civil War. Leigh also served in the Philippines and Asheville, NC after this. I have additional pictures from this time, if anyone is interested.
