Jeff seems to have had a really difficult start in life (and Jade's childhood was not easy either). Looking on Wikipedia:
Brazier was born Jeffrey Carl Smith on 27 May 1979 in Bracknell, Berkshire.[5][6] His mother Janette Smith was sixteen at the time of his birth, and Brazier was temporarily placed in a foster home after she became unable to cope.[7] She married his stepfather Robert Brazier in 1985, whose surname he adopted.[8] Together, they had Brazier's younger brother Spencer who has cerebral palsy.[9] After they split, Brazier and his brother lived in a women's refuge in Great Yarmouth.[8] Brazier's biological father, Stephen Faldo, who initially denied paternity, was the skipper of the pleasure boat Marchionesss^, which sank on the River Thames in 1989 after being hit by a dredger, killing him as well as 50 others.[10]
