Origin of the Magenis Name

Many variations of spelling of this name - MacGuinness or MacGenis, Magennis or Magenis, a form still to be found in some places today. In Irish the name is MagAonghusa, i.e. son of Angus. They are descended from Saran, chief of Dal Araidhe in St. Patrick's time and thence to Eochaidh Cobha of Iveagh, County Down. Like the chiefs of many of the great Irish septs Magennis took advantage of the English policy of "surrender and regrant" warly in the seventeenth century; earlier they were often at loggerheads with the ecclesiatical authorities and they showed a tendency to accept the tenets of the Reformation; conforming bishops include two Magennisses - one of the diocess of Down, the other of Dromore. However, by 1598 the Magennis chief of the time, whoe father was officially regarded as "the civillest of all the Irish in these parts," had joined Tyrone (who was his brother-in-law) and thus "returned to the rudeness of the country." A generation later their loyalty to Ireland and the ancient faith was undoubted. The Franciscan Bishop of Down and Connor, Hugh Magennis (d. 1640), was closely related to Viscount Iveagh and many of the Gaelic nobility of Ulster. They were consistently on the Irish side during the resistance to English aggression in that century and after the disasters following the battle of Boyne they were finally dispossessed of their wide patrimony in Co. Down, much of which had been planted with English (not Scottish) settlers after the Cromwellian war. Many of them took service as Wild Geese. The best known of these was Brian Magennis, second Viscount Iveagh, who was colonel of Iveagh's Regiment in the Austrian Imperial Army and was killed in action in 1703. His brother Roger Magennis, third Viscount (d. 1709), served both France and Spain with distinction. The present Lord Iveagh (of the second creation), head of the largest brewery concern in the world - Guinness of Dublin - though not a direct descendant of the lords of Iveagh mentioned above, belongs to a cognate (McCartan) family of Co. Down, This family spent very large sums on improvement of housing and social conditions in the city of Dublin as well as on the upkeep of St. Patricks Cathedral and its surrounding.

Chouteau v. Magenis.

zell." This deed was defectively acknowledged. In partition proceedings between Rankin and Schatzell, in 1828, the entire lot was sold to Rankin. In 1828 said Rankin conveyed the south half of said lot to Arthur L. Magenis. On the 20th of January, 1848, Sophie Chouteau sold and quitclaimed to Rankin the north half of the entire lot. In this deed the deed of 1827 is referred to. Auguste P. Chouteau died in 1838. Arthur L. Magenis went into possession in 1828, and possession under him has continued uninterruptedly until the present time. He made valuable improvements. The plaintiff claimed to recover one-eighth of that portion of the lot which was conveyed to Magenis. The court, by its instructions to the jury, ruled that the divorce of Honey and wife was void; that the deed from Honey to his wife Marie Antoinette Honey was inoperative as a conveyance to the wife. The plaintiff recovered one-fortieth of the lot sought to be recovered. Writs of error were sued out by both plaintiff and defendants.
Pierrie Chouteau was ordered to pay Arthur Magenis by the American Fur Company. It is unclear if it is related to the above.

I believe that Chouteau was the ancestor of Beatrice Paul Marmion (wife of Robert A. Marmion)
Arthur Magenis was a witness to the trial of the Impeachment of Judge James H. Peck, Judge on the United States District Court of Missouri.
