Apart from both Sahagún, father and son, respectively Alonso de Sahagún or Sahagun el Viejo, and Luis de Sahagún, there was another Sahagún, Alonso de Sahagún el Jóven. All of them swordsmiths from Toledo. And all of them had a personal marking to identify their swords, apart from the inscription of their names. I don´t have registers of other Sahagún´s. It must be taken on account that there was also a "Sahagún School" they left for the posterity, so you can find swords from the Sahagún School, formally recognized as that by the scholars on this subject. For more references, please see this document from German Dueñas Beraiz, published in
Gladius magazine:

The markings of 99 swordsmiths form Toledo, including the Sahagún´s, can be seen in:
Claudio del Fraxno y Joaquín de Bouligny
Memoria Sobre la Teoría y Fabricación del Acero en General y de su Aplicación a las Armas Blancas,
Segovia, Imprenta de D. Eduardo Baeza,

I agree with Jim. The blade seems not to be from those swordsmiths. But a very good piece anyway. Yes, to envy, Gene. Probably form Solingen.
My best regards
