Meghan Markle's extended family wasn't invited to the Royal wedding, but that didn't stop them from jetting off to London.
Meghan's nephew Tyler and his brother, Thomas Dooley, arrived at London Heathrow Airport along with their mother Tracy Dooley, who was the wife of Meghan's half brother, Thomas Markle Jr. Despite no invite, the family does have a purpose there -- they will be special correspondents on "Good Morning Britain" ... presumably dishing family deets for Saturday's big day.
Also not going to the wedding? Meghan's father, Thomas. TMZ broke the story ... Thomas decided not to go because he doesn't want to embarrass the Royal Family or his daughter. The decision comes on the heels of the fallout over him selling photos of himself.
