The meaning and origin of the last name Insuasty

The surname Insuasty is believed to have origins in the Basque region of Spain and France, where it is spelled as Insausti or Inzaugaratza in Basque. It is derived from the toponymic name "Inzua" (meaning 'valley') combined with the suffix "-garratz" (meaning 'oak forest'), indicating that an individual lived near a valley surrounded by oak forests. The name was likely brought to the Basque Country by early settlers, possibly during the medieval period. Over time, variations in spelling and pronunciation have occurred due to factors such as regional dialects, migration, and record-keeping errors. Today, the Insuasty/Insausti surname is predominantly found among the Basque population but can also be encountered elsewhere due to historical migrations and assimilation.

While the majority of Insúaсты reside in Spain, particularly in provinces such as Gipuzkoa, Biscay, and Navarre, some families can also be traced in French Basque Country, particularly in the Pyrénées-Atlantiques department.
