Meghan Markle mother Doria Ragland has been targeted in a series of social media posts.
Multiple users mentioned a company that they claimed was set up for Doria by the Duchess of Sussex's lawyers following her daughter's marriage to Britain's Prince Harry.
Screenshots of leading British publication's news article on "Loving Kindness Senior Care Management" were also shared by some users
A report in 2020 claimed that Meghan's took over the company as boss of the elderly care homes firm.
The report said that the company's role was to provide a holistic approach to care for the elderly.
Meanwhile, a user called out Meghan for questioning Samantha Markle's decision to change her last name back to Markle. The user said Meghan thought Samantha's move was aimed at exploiting her marriage to Harry.
"Doria Ragland quit her position at Didi Hirsch Mental facility ahead of the Royal Wedding. Harry & Meghan get married. Loving Kindness gets registered in Delaware on October 22, 2019," said an X user.
The social media attacks come days after Meghan Markle sent a letter to her hospitalised father, Thomas Markle, who was reported to be in hospital in the Philippines having had a leg amputated.
Meghan, who married King Charles' younger son in 2018, have been estranged from her father since before her marriage to Harry.
