Notes:
Before January 1891, matches were controlled
by three officials: two umpires, one in each half of the field of play,
and a referee who sat on a chair outside the field at the half-way line.
In 1891 the umpires were relegated to the side-lines and became linesmen
or assistant referees, while the referee took charge of the match and
operated inside the field.
For this very reason, all umpires
(that we know of..) before 1891 are included in the referee's listings.
