The research I did last winter looking at football in Bedlingtonshire after World War 2 showed that a team from Netherton Colliery played in The Miners Welfare League for 4 seasons from 1948/49. They also had a Reserve Team that played in the Ashington Welfare League for one season only in 1948/49. The names of the players that I managed to get from the Morpeth Herald and/or Blyth News are in one of the jpegs below.
It just might be that some of the Netherton lads from before the War were still playing after the War
The other jpeg shows all the teams that I could find that were playing for the 5 or 6 years after the War.
Most of the teams did pay the players (as part-timers), so it wasn't uncommon for the better players to play for a different club (colliery/village) if the money was considered better. Players could also sign and play for more than one club, provided they were in different leagues.
