Very interesting Jose. I got my info from a book on US Hispanic Name Etymology. The root of the word Gabalda means "abundant pasture" according to this source. The word seems to have first been developed in southern France which is historically a Basque region. That Cuenca has a town named Gabaldon could mean that some basques (or people who married into a Basque family) moved there from northern Spain. Its only a short distance from the basque region. The origin seems to point to a Basque source. If the name first came from Ireland ("Gabali") and arrived to a Basque region then I would say that it has more of an Irish- Basque origin. That it became Gabaldon (an Hispanicized version)was a later event. I was looking for the earlier origin of the word so technically my message may not be ill-informed. What do you think of all this?
