Lalo (his real first name is Eduardo, but I think only gets called this three or four times) Salamanca is a character from the show Better Call Saul, introduced in Season 4, played by Tony Dalton, who by the way 110% deserved an Emmy nomination and win for his portrayal of the character.
Honestly this is actually a good name and I really like it! I wouldn't expect it to be a variant of Eduardo, but nonetheless, a very nice, strong name.
I pronounce it LAY-lo, though I realize that's not authentic. I made it up for a character in a story and pronounced it this way before I realized it was an actual name. I was very surprised the first time I saw it on a real person.
