The Lagina family had four siblings; Rick, Marianne, Marty and Teressa. The siblings were very close to each other from a young age.
All the siblings are currently married. The youngest of all, Teressa is currently married to John. This makes the Lagina family, John’s in-laws. With that relationship, John is the brother-in-law of both Rick and Marty.
With this relationship, both the sons of John who have been involved in the show for a long time are the brother’s nephews. And both Rick and Marty love their nephews very much.
