Henry Burleigh, Viscount Timmons, is the sharp-tongued young son of Lord Burleigh in Janeway's Gothic holonovel, one of the two children she is engaged to teach as governess.
Henry is a holodeck character in the Victorian holonovel Janeway plays in Voyager's first two seasons, in which she takes the part of Lucille Davenport, new governess to a widowed nobleman's household. He is seen in Learning Curve and again in Persistence of Vision.
He is a stiff, superior boy who insists on his title and makes it plain he has no wish for another governess, in contrast to his gentler sister Beatrice. Both children are clearly hiding something about their late mother and the forbidden upper floor of the house, the mystery that drives the story.
Janeway's first lesson with the pair is cut short when Crewman Dalby blunders into the programme, and the novel is never finished: after the Bothan encounter turns its characters into hallucinations, she sets it aside.
