Phoebe Louise (Usonia) is out of Inka XVIII, an imported Holsteiner Verband Approved mare by the legendary Cassini I. Phoebe's sire is Rebel Z I, a very scopey stallion, who competed successfully in the International jumping arena. Rebel is the full brother to Retina Z, Ludger Beerbaum's famous mare.

In June 2011 this lovely mare started in professional jumper training at Windsor Farms, three weeks before entering the Hits Series in Culpeper. She finished the Series at Level 2. Phoebe is a kind, honest and uncomplicated mare. She is easy to ride and handle and is the perfect partner for the accomplished amateur rider. Also, as an AHHA Approved mare, she is well suited for Holsteiner breeding.
