Hi. My last name infante comes from my grandfather in michoacan Mex. His great grandparents are from Sinaloa and they were related to Pedro infante's aunt. The surname infante is not native its from Italy. Portugal. I was told that italian infante family came to mexico for work and migrated through trains. And thus separated and each one started their own infante family. Someone in my family has old post cards from when they would communicate that proves this. But I'm not close to that side of the family. Antonio infante was the name of the great grandfather as far back as I can trace maybe someone knows.
