John Keegan (2) (1819–1893)

[excerpted from Dictionary of Irish Biography]
John Keegan started school locally, then, after the family moved to Moate, attended a school at Moyvore, acquiring sufficient education to enable him to join the ordnance survey. Keegan had himself transferred to the north of England. Keegan became a railway surveyor, but the sudden collapse of the boom and his wife's poor health caused him to return to Ireland and obtain employment with the board of works supervising famine relief schemes in the midlands near his home town. Before long he rejoined the ordnance survey and did many more years' service. After retiring he worked privately in England and in Ireland.
