In 1955 he married Lucinda Gaye
Leveson-Gower, daughter of Brigadier General Hugh Nugent Leveson-Gower, RA and his first wife, Avril Joy Mullens (later fourth wife of
Ernest Aldrich Simpson, himself the second husband of
Wallis, Duchess of Windsor, whose love affair with King
Edward VIII led to the
1936 abdication crisis). In 2006,
Michael Brown, a former Conservative MP from 1979 to 1997, stated that Le Marchant had tried unsuccessfully to seduce him. According to former-MP-turned-journalist
Matthew Parris, Le Marchant was a "repressed homosexual". ==References==
