father and son boxers

[CutMeMick]

I believe Guty Espadas Jr. and Sr. were the first father/son combo to win world titles.

Good call on the Espadas..
You also have the Montiels, pops never won a title but was really good.
Matter a fact I think the Montiels are the most extensive boxing family ever.
Uncles, brothers and cousins have all boxed. I think total theirs been 5 of them.

Felix Trinidad Sr. & Tito Trinidad, Sr. won local titles but didn't have anywhere the type of success that Tito did, turned out to be a better trainer than a fighter

Not a lot of people know this but Tito Sr. fought the great Salvador Sanchez. Tito was 7-3 while Sanchez was 31-1.
Sanchez TKO'd him in 5 rounds.
