I’m sure I read somewhere that Michael Salisbury and Graham (?) Salisbury did a game together in the Championship (?). I think it was Graham Sailsbury’s last game and Michael was 4th official. I may be wrong, but I seem to remember seeing that somewhere. That is Father-Son rather than brothers or twins.Sunny Singh Gill and his brother Bhupinder Singh Gill are the only brothers I can think of that have been appointed to a game together
