[1] He was the eldest son of the judge and landowner Sir Robert Bagod, of a family which had been settled in Dublin since the twelfth century.
Sometime before 1303 Nicholas, Archbishop of Armagh assigned him £100 a year from the rents of Baltray, County Louth "in return for his good services".
[3] At first, he resolved on a clerical career, and advanced as far as a canon of St. Patrick's Cathedral, Dublin, but then decided to follow his father into the service of the English Crown.
His career followed his father's closely: he served as High Sheriff of County Limerick 1302–3, was knighted around 1308 and became a justice of the Court of Common Pleas (Ireland) in 1307.
In 1310 he was appointed a justice in eyre, for Dublin County only, along with Walter de Cusack, Hugh Canoun, David le Blond and others.
