While doing some research, I discovered that Oscar and Booker T are related through the Heldenbrand dynasty and share Jet Breaker as a paternal grandfather. CH Rosend's Booker T, SOM/CGC/TT was an amazing and deeply-loved boy who belonged to Christina Ghimenti of Pawprint Boxers. You can see Booker T's line here. I've long admired Christina's ethics, high standards and devotion to the breed. I mourn Booker T's passing, but I'm happy that Christina has acquired more boxers to nurture and show.
