Buenechea

Buenechea is the Spanish spelling of a Basque surname which also occurs in the variants "Bonechea, Buonechea, Boenechea" and "Bonachea". The modern Basque spellings are "Buenetxea" and "Bonetxea". This surname is not common; Buenecheas and Buenetxeas between them number fewer than 100 in the whole of Spain, for the most part located in Gipuzkoa, where diocesan records indicate only around 1000 persons have been born with this name and its variants in the 300-year period 1600–1900. It is made up of the elements "buen, bon" (corruptions of "güen < goen < goien", 'upper') + "etxea" ('house'). The name therefore is originally related to "Goyenetch(e)", "Goyenech(e)" and "Go(i)enetxe".
