Calvin Crittenden was a human and the father of Carrigan Crittenden and left her Whipstaff Manor after his death. However, shortly before he died, he met Jade McFadden, whom he believed was his ancestor's granddaughter. And he was right. So, he wrote in the will should anything bad happen to Carrigan, Jade would become full owner of Whipstaff Manor, back to its rightful owners: the McFaddens.
