Arthur Yard was a Grayson citizen, soldier of the Grayson Army, and an armsman of the Harrington Steadholder's Guard.
He lost an uncle and a cousin at the First Battle of Yeltsin's Star, and another cousin survived the Battle of Blackbird only because Honor Harrington insisted that all life pods be picked up. (HH4)
Yard occasionally substituted on Steadholder Harrington's travel party. (HH5)
