What are the first names of the people that play together consistently?
In the small midwestern town of Kings Row, in 1890, five children know and play with each other: Parris Mitchell, a polite, clever little boy who lives with his grandmother; pretty blonde Cassandra Tower, daughter of the secretive Dr. Alexander Tower and a mother that is seen only through the upstairs window; the orphaned but wealthy and fun-loving Drake McHugh who is best friends with Parris; Louise Gordon, daughter of the town physician Dr. Henry Gordon; and the tomboy Randy Monaghan, from the "wrong side of the tracks,"whose father, Tom, is a railroad worker.
 
Parris is both friends with and drawn to Cassandra, whom the other children avoid because her family is "strange". They play together regularly. The boys are best friends, and Randy plays with the boys sometimes as well. When Dr. Tower takes Cassie out of school, and she is confined at home, and Parris does not see her for many years.
