Rodrigo de Vera was present at the 1540 muster as an unassigned horseman. There are several very late documentary sources for a Rodrigo de Vera which may pertain to the expeditionary. However, that leaves a gap of about forty years between the muster and the later documents.
1540-1550:
1540, Feb: Muster in Flint & Flint, Documents, Document 12 [2 horses, native arms]
1580-1590:
?Catálogo, Resumen e Índices, 2455, AA290 [fol.541: Mexico 6 Apr 1581, Reserva de fianza, Gonzalo Rodríguez, tratante en Campeche, residente en México, se obligó a que Diego Baena, vecino, no pagará cosa alguna por razón de la fianza, que a ruego del otorgante quedó a pagar a Juan Guerrero, vecino, de 86 pesos y 4 tomines de oro común, por razón del arrendamiento de dos tercios de una casa en que vivía el otorgante en la callejuela de la vuelta de los portales de Juan Guerrero y lo firmó así al pie del arrendamiento, porque no sería justo que Diego Baena fuese molestado ni lastase o pagase la dicha deuda. Firmó. Testigos: Hernán Vázquez, Rodrigo Vera y Diego de Santa Cruz, vecinos]
