Ó Maol Chonaire was a member of the
Ó Maolconaire brehon family of north
County Roscommon in
Connacht. A member of the Sliocht Pháidín, his genealogy was
Fearfeasa mac Lochlainn mac Séan Ruadh (died 1589) mac Lochlainn mac Paidín Ó Maolconaire (died 1506). He was thus closely related to
Muirgheas mac Pháidín Ó Maolconaire (died 1543) and his descendants,
Fláithrí Ó Maol Chonaire (died 1629) and
Muiris mac Torna Ó Maolconaire (died 1645). It has been suggested by Eoin Mac Cárthaigh that Fearfeasa's lands were in the townland of Creta, parish of Kiltrustan, beside that of his father, Lochlainn, who lived in Lisheen townland. Páidín Ruadh Ó Maol Chonaire, who retained two-thirds of his lands in Ballymulconry in the 1650s, may have been Fearfeasa's brother. Peter (fl. 1701), son of Fearfasa, was poet to the
O'Róduighe, and lived in
County Leitrim. ==The Four Masters==
