Extremely rare, currently present in the Como area, it should derive from an ancient medieval toponym Leuco (Lecco), of which we have a trace in a charta venditiones of 975 in Calco (BG): "... venditio Attonis comitis de Leuco de pluribus praedis in variis territorii bergomatis viciis .... ", and in a parchment of 1146 where a converso originating from the countryside east of Como is quoted:" Lanterius de Leuco ", a second hypothesis derives it from the ethnic leuki, a Celtic population, it could derive from the Latin nomen Leucus of which we have an example in the Civil War of Ennio Lucano: "... and Biturix longisque leues hypotheses provided by Ubaldo Leuchi The presence in the Como area is a descendant, like all those present in Italy, France and California, of the original lineage of Filattiera (MS) in Lunigiana. One of the first Leuchi was a notary Matheus Leuchi who wrote an act of the Marquis Malaspina of the Lunigianese branch. Later on they were Vessilliferi always of such marquises. Fallen in disgrace, for three centuries sharecroppers of the Ferrari family whose historian Pietro Ferrari verbally told my great-grandfather that the first Leuchi in Lunigiana was the transformation of a surname originating from Pannonia that carried a soldier who settled in Filattiera. hypotheses provided by Carlo Ferrari Leuchi would seem to derive from the color of the hair, leucos in Greek means white, and probably was the name given to a family of Lombards so blond as to seem white. (more details can be found in the Historia Longobardorum by Paolo Diacono. The descendants of Leuchi by Filattiera are still predominantly blond.
