Ero Fernández, conde de Lugo - Who were his Parents?

As far I can discover his ancestry is unknown. Not just unknown to us, but unknown to anyone. There are some late sources that pretend to give his ancestry but no contemporary evidence. If anyone has real sources, primary sources that prove his parents that would be wonderful!

Good morning friends administrators of Froila Fernandez's profile, nice to contact you! I located on the pedigree website the ancestry of the holder's brother, and I would like your approval to add it! Thanks

add him!
