Good assumption, however there are also hundreds in the US, mainly near Washington, DC and Baltimore. I think that I was able to translate enough to figure out that we have the same family. Regarding the famous decendents one can include the new First Lady of Bolivia, Ximena Iturralde de Sanchez de Losada who is a direct decendent of Juan Diego de PALACIOS (Santander, Spain) & Manuela Rufina PINTO (Moquega, Spain). Others include Abel Iturralde Chinel, former Sec. of State, And José Agustin de PALACIOS PINTO, Governor of La Paz., and quite a few others. Perhaps we can exchange GEDCOM files?
