Michelle Dockery says it's a coincidence Downton Abbey and royals both have a baby George Michelle Dockery as Lady Mary in Downton. The actress may not return for the fourth series. Picture: ITV Source: Supplied MICHELLE Dockery has warned against jumping to conclusions about how her character's baby on Downton Abbey and the British royal infant ended up with the same name. George proved the name of choice for the fictional boy born to Lady Mary on Downton and the real one in line to be the king of England. Dockery called it an "amazing" coincidence, but said the drama's baby was named before Prince William and his wife, Kate, picked George for their son. And while Dockery has heard that William and Kate are fans of Downton Abbey, she doesn't suspect that it inspired their choice. Downtown Abbey returns for season four in Britain in September.
