How are the names of Spain arranged?

Spanish names often have three or four paragraphs. The first one or two paragraphs are my name, the last one is my father's surname, and the last one is my mother's surname. Generally, my father's surname is my surname, but a few people use my mother's surname as my surname. For example, Diego Rodriguez DE Silva y Velasquez is translated into Diego Rodriguez de Silva-Velazquez, where DE is a preposition, Silva is the father's surname, Y is the conjunction "he" and Velasquez is the mother's surname. Married women often remove the mother's surname and add the husband's surname. Usually, oral address often refers to the father's surname, or the first name plus the father's surname. Take Francisco Franco, the former Spanish head of state, as an example. His full name is Francisco Paolino Hermenegildo Teodoro Baamonde. The first four paragraphs are people's names, the penultimate paragraph is father's surname, and the last paragraph is mother's surname. When abbreviating, use the first part of the name plus the father's surname.
