Samantha, Meghan's white 53-year-old relative who is suffering from multiple sclerosis, reportedly tried to pull a surprise visit and ran into Palace security as she planned to confront the newly minted royal.
Meghan Markle has fitted seamlessly into the royal family from the moment she started dating Prince Harry - from bonding with the Queen's corgis to getting an early invite to spend Christmas at Sandringham with the Windsors. After undergoing heart surgery, the 74-year-old was unable to attend their big day.
Samantha has maintained that she went public with her feelings towards Meghan because she feels her father, Thomas Markle, deserves respect and that he shouldn't have been isolated.
Meghan doesn't seem to respond to Samantha's requests as she has been bad mouthing her and her husband Prince Harry on social media since their wedding. She was accompanied by her partner, who pushed her in a wheelchair.
She soon took to Twitter and wrote, "Everybody would love to know what's in that letter".
During the same trip, Samantha also did a TV interview with London's Channel 5 where she apologized to Meghan.
Samantha wants to tell Meghan that it's "water under the bridge" and acknowledge the fact that things between them got "out of control".
Coral's Harry Aitkenhead had said: "It's Prince Harry's 34th birthday this weekend and with the couple making no secret of their desire to start a family, we think that it's nearly inevitable now that the latest Royal baby will be arriving in 2019".
"I just think that families can be this way when there's confusion and when people are hurt". "I was hoping maybe we would have the chance to speak - that she would know I was here".
