Jan, something that might be worth noting: These men would not be referred to as "soldiers". That term is customarily used to refer to a member of the US Army. The first two of these men would be described as sailors, and the third as a marine.
Info about "hometown" and next-of-kin contained in Nat'l Archives databases is available online. Accessing those sources I found the following :
Joe O'Neil Powers, Storekeeper 3rd Class, USN Hometown: Constantine, MI Father: Mr. Earl Powers, Constantine, MI.
Roy Wallace Powers, Shipfitter 2nd Class, USN Hometown: Long Beach, CA Wife: Wanda Jessie Powers, 2339 Carrol Park, North Long Beach, CA.
Abner Franklin Power, Private, USMC Hometown: Clinton, OK Mother: Mrs. Louada Venamon, 508 1/2 Frisco Street, Clinton, OK.
