RODRIGUEZ SOREASU If the surname is Rodriguez Soreasu, it probably comes from Araba, and that show us that there was a man called Rodrigo Soreasu, and he had a son named XXXXX Rodriguez Soreasu in the XVI century, In this Century began the tradition of giving to the children the same surname as the father,s one, so the Rodriguez that were a patronimic, became a surname. The tipical basque surnames were the names of the baserriak or farms, people had his christian name and used as surname the name of the house in what they lived, but in Araba were mixed the use of Castilla (christian name and the patronimic) and the basque use, so they used Chr.name Patronimic and Surname of the House.

Now the question is, Is Soreasu a name from Araba or from Gipuzkoa, or in other words where did Rodrigo Soreasu came from?

Jaime Kerexeta in his "Diccionario Onomastico y Heraldico Vasco" says

SOREASU: In Gipuzkoa, variation of SORAZU (but there also exist the surname SORASU)

SORAZU: In Zumaia and Tolosa, the meaning is place of prairies (SOROA means prairie, or field) and the sufix ZU or TSU means abundance

SORASU: In Donostia and Itziar,(Gipuzkoa), variation of Sarasu

Sorasu or Sorazu: house in Itziar (Deba)

Sorazu: house in Zumaia (Oikina valley)

Sorazo Aundi and Sorazu Txiki, Deba (quarter of Elorriaga)

The only solution is make your Genealogic chart (and many times you don,t find anything)
