How do Spanish last names change from generation to generation?

ok so i have to do a project for spanish, i am supposed to change my family trees last names to follow ';spanish last name '; guidlines, my teacher gave a vague example, but i cant really figure it out, I know as a Female, you are born as one name, and you get married and keep the 1st last name of your father and adopt the second last name of your husband. but i do not know for example, when you are born, is your last name the same as your fathers, or a combination of your fathers and mothers? Im just getting more and more confused, so I'd appreciate it if someone could clarify this a little bit. Also A little simpler question, to me what relation is My sisters husband to me, in spanish? Thanks!How do Spanish last names change from generation to generation?
Hey. This is particularly difficult to understand for almost anyone who is not Hispanic. 1. This is what happens: In all Spanish-speaking countries (to say: Spain, Mexico, Equatorial Guinea and many more) we bear two family names and NOT one like in many other counties (ex.: the US).



Let's pretend your name is Mar铆a. Your father's last name is P茅rez and your mother's is L贸pez. Your complete name will appear as Mar铆a P茅rez L贸pez and YOU ALWAYS USE THIS NAME LIKE THAT. In the case of marriages, you preserve your maiden name; however, there is a detail: Let's say your name is Mar铆a P茅rez L贸pez and you marry some Jos茅 Gonz谩lez S谩nchez. Your name will continue to be Mar铆a P茅rez L贸pez, but you will also be referred to as Mar铆a P茅rez ';de'; Gonz谩lez (the husband's name, actually stating that you're his wife... and that you sort of ';belong'; to him. I personally don't agree with this designation). This latter reference is not of official use and your name stays the same in all of your papers.



In the U.S. al Hispanics that arrived have to keep only one last name (in this case, their father's). Once again, if you're Mar铆a P茅rez L贸pez, there you will only be Mar铆a P茅rez. Centuries ago, many immigration officials messed up by making those two names one, and make you Mar铆a ';P茅rez-Lopez';. It is complicated, indeed!!! But you may read the first paragraphs again, ommitting this one and you will get a broader idea.



2. If you麓re talking about the translation for ';brother-in-law';, that would be a ';cu帽ado'; in Spanish. Hope this helps!How do Spanish last names change from generation to generation?
As Hispanics when we are born we get a combination of both parents last name. EX: Maria Lopez Chavez and Fernando Hernandez Castillo. When Maria gets married she loses her mother's last name and adopts her husband last name with ';de';.

Now she becomes Maria Lopez de Hernandez. And if they have childrens their last name will be Hernandes Lopez and so on...



Your sisters husband is your cu帽ado in spanish
To start with the easy question: your sister's husband would be your brother-in-law... so you might just say herma帽o. Here's something i found in my Spanish book.



';Francisco introduces himself as Francisco Garc铆a Flores. Garc铆a is his father's last name, and Flores is his mother's. In Spanish-speaking cultures most people use both last names. Some women add their husband's name after the word 'de'. So Francisco's mother's name might be Anita Flores de Garc铆a in many countries. In the U.S, some Spanish-speaking women use just their husband's name, as Anita Garc铆a does here.';

I hope that helps!
