Courtney

One of Jane Lane's nieces (possibly the only one), daughter of Jane's oldest sister, Summer Lane. Courtney and her brother Adrian appear in "Lane Miserables."

Courtney closely resembles her mother, unlike Adrian. Little is known about her, including whether or not her last name is "Lane." Like all four of Summer's children she tends to run away a lot, and usually seems to travel with Adrian. It is unclear where she resides in the family birth order; since she and Adrian seem close in age it is possible they are twins.

A teenaged Courtney appears in Wouter Jaegers' comic Growing pains where she's wearing Jane's old outfit which Amanda had given to her despite Jane's objections. ("Summer will KILL me!") Being pushed by her grandmother to thank her aunt for the clothing, Courtney thanks Jane halfheartedly before nervously adding that Jane should stay away from Summer for a while.
