Maurice FitzGerald, 2nd Earl of Desmond [SEP] father
Maurice FitzGerald, 2nd Earl of Desmond
Maurice FitzMaurice FitzGerald, 2nd Earl of Desmond (d. 1358) (Maurice Óg) was the son of Maurice FitzGerald, 1st Earl of Desmond, and his first wife, Catherine de Burgh. (Some sources list her as Margaret.) 
The 2nd Earl married Beatrice de Stafford, daughter of Ralph de Stafford, 1st Earl of Stafford and Margaret Audley, but died without any male issue, and was therefore succeeded in the Earldom of Desmond by his half-brother Gerald FitzGerald
-brother to Maurice FitzGerald, 2nd Earl of Desmond.
Maurice Fitzgerald, 2nd Earl of Desmond, would have been followed by Gerald's older brother, Nicholas, but Nicholas was described as "an idiot", and so was passed over for the earldom. Because of this, some older histories list Gerald as the 4th Earl.
Life.
In 1356 he was brought to England as a hostage for his father's good behaviour, but as his father died that same year, he was soon released.
