A source tells ET that Meghan’s mother, Doria Ragland, is expected to spend some of the holiday with her pregnant daughter and her son-in-law. It’s expected that Doria will receive an invitation to attend church with the royal family at Sandringham, the royal estate in Norfolk, England, where the royal family traditionally celebrates the holiday.
In contrast, Kate Middleton's parents have also been guests at the Sandringham Christmas morning church service but typically stay with their daughter and Prince William at their nearby home nearby, instead. Kate and William have alternated holidays, spending Christmas at Sandringham and at her family’s home in Bucklebury.
"It's a mark of the Queen's respect for Meghan and an acknowledgment that she doesn't have any other relations in this country -- unlike Kate who has the support of a very close family," a source tells the UK outlet.
