John seems to have divided his time between Boyle and a house in Dublin near Baggotrath Castle, on present-day Baggot Street.
[1] Under King James I, having gained the reputation of being an exceptionally useful and versatile public servant, John held many profitable offices, and by the end of his life, he owned land in twenty-one counties.
He became Muster-master for Ireland and Clerk of the Cheque in 1609, with a reversion in favour of his eldest son Robert, and a Commissioner for Compositions in 1611.
He sat on the Council of Munster, and at different times was authorised to act as temporary governor of Connacht, Leinster and Ulster.
Elizabeth Carew's background is obscure, although she appears to have been born at Old Leighlin in County Carlow; her father's name is variously given as George and Thomas.
