Not sure if George Jr's had children who may have stayed here in the Ironwood area, but I do know a Ross family. If you go to The Gogebic Range City Directory at
http://mattsonworks.com/ you will find these Ross families:
1928
Erwin Twsp: Ross, Charles (married) surface laborer
Ross,
Ewin, man home
1927 Wakefield: Ross, John (married)
Castile Rd laborer
Ross, Mrytle teacher
1938
Erwin Twsp: Ross, Charles (Mary)miner,
Newport Mine
Ross, Edward
1947 Bessemer: Ross, Mae (widow of John) school comm.
1947 Ironwood: Ross, Andrew
Ross, Charles (
Belle)
Ross,
Sophie Ross, William (Emma)
1947
Erwin Twsp: Ross,Charles (Mary)
Timberman,
Newport Mine
Ross, Lawrence (Elvie) Gogebic Insulation Co.
Since this area is a very old mining region and the main employer for many years you may want to look for list of deaths from mining disasters. Tilden mine is in
Bessemer,
Newport Mine is in Ironwood but there are several in the region. Check above website for the mines, cemeteries, photos as well as who were living in the towns.
Good luck, hope it helps some
