Surnames for Reploids?

I did a bit of snoopin' on the fanon page for TVTropes and apparently, there were theories and rumors circulating ages ago that the Reploids apparently had family names belonging to a family. While Reploid family members are indeed a thing, it's still something to note. Although, it does ask the question of where Reploids are actually coming from. If they're being mass-produced, who or what regulates these? Of all the things we do know about Reploids, I don't believe this was ever actually mentioned in any of the games. I certainly have not heard of a Reploid factory. I dunno, maybe I'm going on a tangent. I was just curious.
