Del Boy never marries. He has had many girlfriends, a fact that is the subject of numerous sarcastic comments by Rodney. He finally meets his partner Raquel Turner (whom he calls his "significant other") in the 1988 special "Dates". Del's mother Joan dies on 12 March 1964, apparently after a long string of illnesses. His lazy father Reginald leaves three months later (on Del's 16th birthday), taking most of their money and even Del's birthday cake. This leaves the teenage Del as the family's sole breadwinner, looking after his grandfather and Rodney, his half-brother who was born around thirteen years after him
Damien Trotter remain oblivious to Damien's bad behaviour when he was younger, they did gradually become stricter with him in the final episodes and Rodney frequently calls him or refers to him as "Rat Boy". He was named after Del and Raquel could not decide on a name for their unborn baby (Raquel thought of Aron, pronounced "air-on", but Uncle Albert thought the kids would nickname him "Aron a G-string" and Del thought Troy, but the name Troy Trotter was instantly dismissed), so Rodney sarcastically suggested that they name him "Damien" as Rodney was convinced that the baby would be born half-demon.
