He was married three times. • Joan, married firstly
Richard Plunkett, 2nd Baron of Dunsany, and secondly her cousin Sir Maurice FitzEustace of Coghlanstown, eldest son and heir of Sir
Robert FitzEustace. • Jenet, married Sir Walter Delahide: both played an important role in the rebellion of the Earl of Kildare's grandson,
Silken Thomas, as did their sons. Jenet died in prison under suspicion of treason, and her sons were attainted as traitors. • Margaret, married Christopher Rochfort • Maud, married Thomas Marward, titular
Baron Skryne • Katherine, his second daughter by Margaret d"Artois,
born out of wedlock but legitimated by Act of the
Parliament of Ireland in 1475–6. He also had an illegitimate son: •
Oliver FitzEustace, who became
Chief Baron of the Irish Exchequer; since Oliver seems to have been mentally deficient, his father further extended his influence by appointing Deputies to act on his behalf. The barony became extinct on his death in 1496, but his nephew
Thomas, son of his brother Richard, was created
Viscount Baltinglass in 1541. Sir
Maurice Eustace, a wealthy and influential member of the FitzEustace clan who became
Lord Chancellor of Ireland, accepted the title Baron Portlester at the
Restoration of Charles II, but then changed his mind, apparently because, like Rowland, he had no legitimate son to succeed him. ==Reputation==
