de PERALTA or PERALTA surname of Spain. I've found this name all over the world. I am working my way back to Spain from the Philippines.
I was told that by my dad that he dropped "de" from his last name because it was shorter and easier to write. Records of older generations have "de PERALTA".

de PERALTA is the name I found associated with my Grandfathers.

Felix de PERALTA married Cristina CABUDOL and they had a son Pedro
de PERALTA. I found that they had six children.
