Didacus [Diego]  Blasius 

Braga [?]; earliest reference, motu proprio of [February  1519 ] [see   FREY  (1955): 66]; notarial list of September  1522 .

 FREY  (1955), p. 66 mentions a bull dated 26 December  1517  giving a benefice to a Didacus Blasius, described as a cleric of Braga and a member of the household of Gundissalvus de Salazar, but this Blasius is not further identified as a cantor capellanus.
