Being without a father and starting religious studies, he took the family name from his mother, following the tradition (which would explain why in some documents he appears as Antonio Álvarez).
In Albandi documents he continues to appear as the parish priest until 1661, when he is relieved by his nephew Xuan Rodríguez Reguera.
According to González Posada, Antón de Marirreguera himself asked his nephew to burn some of his papers just before his death, because he did not want it to be said that a priest "amused himself doing this sort of thing".
The first edition of his works was made by González Posada, who published the «Pleitu ente Uviéu y Mérida» and the first octave of «Dido y Eneas» in Memorias Históricas del Principado de Asturias y Obispado de Oviedo (Historical Memories of the Asturian Principality and the Oviedo Diocese) of 1794.
With this motive, an adaptation of «L'ensalmador» was performed, arranged by Lluis Antón González and directed by Xulio Vixil.
