The Scottish Nation entry for Sinclair, hosted at Electric Scotland, gives the tale. The king asked his nobles whether any had dogs that could take the deer, and Sir William offered his head that his two favourite dogs, Help and Hold, would kill it before it crossed the March burn. At the burn Sir William dismounted, apparently in despair, but Hold stopped the deer in the water and Help came up, drove it back and killed it on the winning side of the stream. Bruce granted him the lands of Logan house, Kirton and Earncraig, and in the superstition of the times he built the chapel of St Katherine in the Hopes, in the parish of Penicuik.
This is a family tradition, recorded centuries after the time of Bruce. St Katherine's in the Hopes is now beneath Glencorse Reservoir. The legend is placed here in the Pentlands near Glencorse and is a folk tale, not an event that can be proved.
