Put forward by Grand Master Ramon Perellos y Roccaful, in 1707 Leocata was recommended to the Master of the Dominican Order for the office of Vicar-General of the Dominicans in Malta on behalf of the Sicilian Prior Provincial, a proposal which was accepted the following year (1708).
Between 1729, Leocata was elected Priory to the community at Vittoriosa, Malta, and a year later, in 1730, to that at Valletta.
