Anthony le Flamenc was of Flemish ancestry (as his surname indicates),[2] and his forefathers had long been settled in the Holy Land before he rose to prominence in Frankish Greece.
[2][4] Anthony is also known to have had estates at nearby Koroneia and Patricio, possibly to be identified with the modern village of Ypsilantis, where a medieval tower is located.
In 1305 he was among the witnesses to a deed relating to her property in the Low Countries (from which both of them hailed) and he was present with his son at her second engagement with Charles of Taranto in Thebes on 2 April 1309.
[4] In 1308, the Republic of Venice accused Anthony, Guy, Rocaforte, and Boniface of Verona of plotting to seize the Venetian colony of Negroponte.
[4] On 15 March 1311, Anthony fought in the Battle of Halmyros against the Catalan Company and was one of the few survivors, though he was captured and held for ransom, as implied by the presence of his name in a list of correspondents of the Venetian authorities in 1313.
