Gontinha Eriz - relationship between Gontinha Eriz and Ero Fernandez

I'm writing to see if we can clarify what appears to be a major inconsitency in that Gontinha Eriz (Gontinha Eriz... was born long after her father Ero Fernandez (https://www.geni.com/people/Ero-Fernández-conde-de-Lugo/60000000014...) died. Obviously this isn't possible. So either Gontinha's year of birth is wrong, Ero's year of death is wrong, or this particular Era is not Gontinha's father.

What are your thoughts here? Any suggestions on how to correct this? Please let me now your thoughts here.

muchas gracias,
attentatment,
