I just used my nickname and first letter of my last name.  My full first name is Rodolfo, the Spanish version of Rudolph.  My dad was named after some Austrian Prince who killed himself because he was told he couldn't get married to who he loved.  It got passed to me.  This is why my son is named Matthew

Yup, kinda sad story. He was the son of FJI, who had no luck with his family. Wife stabbed, son shot himself, Franz Ferdinand also got shot and there were even more such cases, I think. Anyhow, doesn't matter … Is your last name of Hispanic origin too?
