Soooo, Dillon is a NORMAN NAME also, Normans are of DANNITE DECENT through ROLLO, my royal grandfather! I have traced the GAELIC lines back to early SPANISH TERRITORY, before ROME, defeated the Gauls. 5 Kings in Ruby Dillon, my granny!

I see a GUYOMAR ALONZO birthdate around 1150 ad, GUYOMAR DE LEON was in France and a NOBLE! I think that Guyomar used the title DE LEON in France to be more antimidating, LEON was where the 7th Legion of the Roman Army was housed. King Ferdinand, one of my grandfathers was appointed HOLY ROMAN EMPORER, so LEON being his territory, likley had that legion! I feel like the same Guyomar in the list of spanish nobles is the same man. I saw around 5 kings in Ruby Dillon, my geandma’s geneology, I believe those were before LEON, when more Gaelic influence was in the people in spainish territory.
