John D. "Jack" Turner was one of several Grand Forks Senators who spent at least a decade residing in the Red River Valley. The others were Sid Adams, Billy Hanrahan, Charlie Hutton, William McNeil, and William "Harry" Walker. All of these men played not only on the 1897 Grand Forks league team, but also on Grand Forks teams of other years. (Incidentally, Billy Hanrahan was the only player to play on the Grand Forks clubs of the Northern League, from 1902 to 1906.) John's brother James, though not on the 1897 league club, played alongside his brother on other Grand Forks teams. A longtime resident of Grand Forks, John Turner moved west after his retirement, passing away at the age of 92 in Billings, Montana.
