Warlop was married to and later divorced from Fernande ('Nandette') Richard; the couple did not have any children. He also had no brothers or sisters. A few of his distant cousins are alive today, living in or near Douai, France. He is buried in the left (when coming from the center of Luchon) of the three cemeteries (all are next to each other) on the outskirts of Luchon, France.
