Matthew Trinneer is Connor's brother. He was with him on the Seatrek cruise. They're 18 months apart in age.
18 months apart? (Poor mom) Were they close when they were growing up?
FYI, Lt.FG, there's another Trinneer sib - younger sister (Megan - but I don't think that's the right spelling) Did they mention her on the Seatrek, Jinx?
