Surname CRAZUT #poland


Hello, a pleasure to greet you.
My name is Carla and my last name is CRAZUT.
I am looking for the origin of my surname.
My great-grandfather was a natural son of an unknown father, and his mother had supposedly given the family name CRAZUT.
Pedro Manuel and his brother Ramon CRAZUT were both born in Venezuela. 
We do not know the name of the great-great-grandmother CRAZUT and how she arrived in the country.
