The number of boys raises the question of whether the girls are simply not included. Visitation pedigrees often leave out the daughters as they did not inherit unless there was no male heir, and their pupose was to show who was entitled to bear the coat of arms, have arms for battle and obligated to supply horse for battle.

In earlier times when the Romans controlled central England and most of the settled world, there was a group of elite military men that were appointed to supply security for the Emperor of Rome. These men were known as the Praetorian Guard. These were not only elite military men, but were also highly educated and powerful men within the Empire, who benefited from the feudal system that the Emperor controlled. Later in history these people began to control the various areas of the world that had been conquered by the Romans and a "title" of "The Praetorian" began to evolve. This person held a powerful political position that secured control of these areas by other than military means. This held the military in check and allowed for a dual military and politically controlled local government. The Praetorian held the powers of a Magistrate, Judiciary, Tax Collector, Military Paymaster and Governor, all at one time. A Praetorian generally came up though the ranks in the military and was appointed by the preceding Praetorian. It was common practice for a Praetorian to appoint his son to succeed him. He could control his sons rise though the military to insure his success.
As the Roman Empire began to diminish, the role of the Praetorian began to diminish. The Praetorians began to insure their power by aligning themselves with the new and prevailing power of the Church. As time passed the position of the Praetorian was changed and other titles began to evolve.
The name Prater was the Anglican version of the Latin word Presbyter, Prater, The Elder and Praetor. Praetorian was a class of people of early Roman times who were Magistrates, Trusties, and Learned Men whose position was usually inherited and passed down in the family. It is believed that a descendant of this class was attached to the Norman and English Crowns and held their power though their connection with the Roman Catholic Church. Our Prater family is believed to have descended from this class of people. The Praters of England held such positions of power through out the country, both of the Crown and Church.
