Millais's father is Ugano Sitte, who died much too early. This was regarded as one of the stallions for the Belgian future. The Clinton son was still at the beginning of his international career, but had already achieved sixth place in the 6-year championship in the past.

The granddam Magestueuse v / d Begijnakker (by Skippy II) gave the sBs-approved stallion Farius de Laubry (by Lux) and Gracieu Begijnakker-Laubry, an AES-approved son of Canturo. In addition, also the 1.40m jumping Care de Laubry (by Coriano Z), the 1.50m jumping Charmeur v / d Begijnakker.

Millais is a powerful stallion with enormous scope and a great character. He always does his utmost on every jump.
