Passage: Through the 1860s, Victoria relied increasingly on a manservant from Scotland, John Brown. Slanderous rumours of a romantic connection and even a secret marriage appeared in print, and the Queen was referred to as "Mrs. Brown". The story of their relationship was the subject of the 1997 movie Mrs. Brown. A painting by Sir Edwin Henry Landseer depicting the Queen with Brown was exhibited at the Royal Academy, and Victoria published a book, Leaves from the Journal of Our Life in the Highlands, which featured Brown prominently and in which the Queen praised him highly.
Output:
What was the name of the manservent that Victoria had in the 1870's?
