[2] Maria Follia is first appeared in contemporary records on 9 August 1330, when her husband William Drugeth drafted his last will and testament in Sáros Castle, Kingdom of Hungary (present-day Šariš, Slovakia), because he prepared for war against the Teutonic Order.
[4] John Drugeth and his family – including the eldest son William – were invited from Naples to Hungary by King Charles I in order to inherit the wealth and power of Philip Drugeth (John's younger brother), who lived in Hungary for decades as the king's most loyal comrade-in-arms, and by the time of his death (June or July 1327) he had risen to be one of the most influential barons.
Hardi considered Maria Follia in her look and appearance was a role model in terms of aristocratic fashion and culture of daily life for many ladies and courtiers at the royal court in Visegrád.
Under the influence of Queen Elizabeth and Thomas Szécsényi, Louis rejected William's last will and testament from 1330, and his younger brother Nicholas Drugeth was not recognized as his heir.
As a widow 's allowance, Maria Follia was able to retain Széplak (Krásna) and Nádasd (Trstené pri Hornáde) in Abaúj County (today both villages locate in Slovakia), where she lived thereafter.
[10] When the queen visited the Kingdom of Naples in the summer of 1343 to promote the interests of her second son, claimant Andrew, who was betrothed to Joanna I, Maria Follia was among the 400 people in her company.
Đura Hardi argues Maria Follia was perhaps not even among the rare but the only court lady of Elizabeth who fluently understood and spoke the language of the ruling elite in southern Italy.
Hardi emphasizes Maria had no legal right to inherit the feudal estate, in comparison to her late husband's brothers, who did not receive an invitation to accompany Elizabeth on her journey to Naples.
Some of William's servants remained in her service, for instance Meynard, the personal physician of her late husband, and Giacomino, who served as vice-ispán of Csongrád County, vice-palatine, then vice-castellan of Óbuda under Palatine John Drugeth.
[13] On 5 June 1358, Maria Follia intended to sell her mansion at Visegrád to her brother-in-law John II Drugeth and other relatives; however she had already given it away as a gift to a Hungarian knight and baron Töttös Becsei, also an influential member of the queenly court.
