◾Abbasi family becomes The Abbasis

◾Banks family becomes The Banks

◾Beale family becomes The Beales

◾Branning family tree becomes The Brannings

◾Butcher family becomes The Butchers

◾Carter family tree becomes The Carters

◾Cross family becomes The Crosss

◾Masood family becomes The Masoods

◾Medeemey family becomes The Medeemeys

◾Smith Family (1980s) becomes The Smiths (1980s)

◾Smith Family (2000s) becomes The Smiths (2000s)
