The Prince and Princess of Wales were possibly made aware of a letter concerning allegations against Thomas Markle as it was sent to their joint office, according to reports. 

The correspondence, which was said to be written by Thomas's ex-wife Roslyn Loveless, was passed from royal protection officers to the Duke and Duchess of Sussex in 2019.

In a statement, Meghan Markle said she had been made aware of "disturbing" allegations against her father in a letter that year, and was assured they were being investigated.
