Paul Adolf G. and Catharina Margarethe von Vultejus from the Hessian chancellor family. The mother, Louise Catharina Grolman (1718-1795), was also a cousin of the father, being a daughter of the real secret councilor, chancellor, and professor of law in Giessen, Dr. Melchior Detmar Grolman, from his third marriage to the chancellor and professor's daughter Maria Clara Mollenbeck.
