I am the sole heir to my families last name. Since the passing of my cousin I am last last remaining male that can pass on his last name, my family said at the age of 18, they will assist me in finding a wife. To be honest, I dont care about our families last name, sure its what I have always had and I have pride for it. But I dont think I could just drop my morals to accommodate their beliefs. I will probable be seen as an outcast to my family for not wanting to have a remaining blood relative to spread the name. What should I do?

Edit: sorry for the trash grammarb etc. Im in under stress.
