The only info I have on them is from this old mag called Celebrity Sleuth Magazine(Vol. 8 # 6/1995). I believe the twoo of them were blondes, the daughter called Rennell Kilner won the Miss Great Britain & Miss Tourism titles in the year 1999.
They both did a topless photoshoot shortly after and starred in this short movie from 1992.
