Initially a washer woman of prince Albert, she was employed by the queen in 1862.
She was responsible for the organization of the queen's chamber staff, handling the contacts with tradespeople and artists, making orders and paying them and answering beggar letters.
As such she had an important position in the royal household, as the queen was generally closer to her chamber staff than to her ladies-in-waiting, to whom she normally had a less personal attitude.
When Victoria died, she was noted to say, that she hoped to be reunited with John Brown and Annie MacDonald.
She received the Queen Victoria Version of the Royal Household Long and Faithful Service Medal in 1892 'for faithful services to the Queen during 38 years'.
