William died in 1325: his property passed to his nephew, Gilbert de Meones, a professional
soldier. He was
Constable of the
castles of
Arklow,
Newcastle Mackynegan and
Powerscourt, and was a wealthy landowner. John de Meones was three times
Lord Mayor of Dublin, in 1331-2, 1335-6 and 1337-8 and Robert de Meones, a brother of Gilbert, held the same office in 1351-2. The de Meones family intermarried with other leading Dublin city families, notably that of
John Le Decer, four times Mayor of Dublin between 1302 and 1326. Le Decer was the maternal grandfather of John de Meones. John's father, another Robert, was a man of considerable wealth, some of which probably came to him through his marriage to Elena Le Decer, John le Decer's daughter, as her father was a rich man, though he gave much of his money away in
charitable works. A John Meones of
Ratoath was appointed Keeper of the Peace for
County Meath in 1382. His son Robert Meones, also of Ratoath, living in 1407, was a Crown official. In 1407 he was instructed to arrest John Brygges, who had been
indicted for several
felonies, and to seize all his
chattels. ==Nicholas de Meones and his heirs==
