Parents of his wife, Mary ( {{user}} ):
Mary's father was Arthur Morstan, a British Army captain serving with the 34th Bombay Infantry in India. He was a man of modest means. In December 1878, Captain Morstan returned to England on leave, checked into a London hotel, and mysteriously disappeared. It was later discovered that he died of a heart attack during an argument with his fellow officer, Major Sholto, who secretly hid his body.
Mary's mother—name unknown. Mary's mother died when she was very young. Presumably, she was European (English), but her health was undermined by the Indian climate. Due to her mother's early death and her father's military service, Mary was raised and educated in a private boarding school in Edinburgh from the age of four.
Her husband is Dr. John Watson. Mary marries her faithful friend and biographer Sherlock Holmes after solving the case of the "Sign of the Four" (the Agra Treasure).
Other Relatives - In The Sign of Four, Mary Morstan states outright that she has no relatives in England.

Beginning in May 1882, Mary Morstan received a box of rare and expensive pearls in the mail every year on the same day from an unknown sender. In 1888 (some chronologies say 1887), Mary received a letter inviting her to meet, describing her as "a woman who has suffered injustice." It is with this note that Mary arrives at 221B Baker Street. During the investigation, Sherlock Holmes discovers that Mary's father died of a heart attack during an argument with his colleague, Major Sholto, over the legendary Agra treasure. The pearls were sent to Mary by the major's son, Thaddeus Sholto, who was tormented by his conscience. At the end of the case, the vast Agra treasure, to which Mary had every right and which could have made her one of the richest brides in England, is irretrievably lost (dumped to the bottom of the Thames). During the investigation, feelings for Mary Morstan and Dr. Watson blossomed. Watson hesitated for a long time to confess his love, fearing he would be seen as a hunter of her potential wealth. When the treasure was discovered to be lost, Watson confessed his feelings. Mary reciprocated. At the end of "The Sign of Four," Watson announced their engagement to Holmes. They married in 1889. Dr. Watson left his flat on Baker Street, purchased a private medical practice, and moved with his wife into their own home. Holmes described Mary as an exceptionally intelligent, cool, and perceptive woman, noting that her analytical mind could be useful in detective work, although he still disliked his friend's wife, as she occupied more of John's attention than Sherlock himself.
