Having managers for Gaelic football teams has not always happened. So early Gaelic Football teams did not have managers. Different people got involved in training and organising teams and doing other jobs to help out. So you could say there was a collective management for teams. So there is no real answer to your question.

Celtic's first ever manager was Willie Maley
I doubt if they had one who was both.
William E. Barclay was the first manager of Everton and also the first manager of Liverpool, working with club secretary John McKenna.
