His family are amongst the most eminent and noble families of Bavaria, with close connections to the Royal House of Wittelsbach, which family is, for Jacobite Legitimists, the senior legitimate line of succession of British royalty.
Two nieces of the Duke of Bavaria are married to two brothers, first cousins twice removed both of Count Claus Schenk von Stauffenberg and of his wife Baroness Elisabeth Magdalena von Lerchenfeld, Countess Monika von Waldburg zu Zeil und Trauchburg to Count Christoph Schenk von Stauffenberg and Countess Maria-Anna von Quadt zu Wykradt und Isny to Count Alexander Schenk von Stauffenberg.
Another niece of the Duke of Bavaria, Countess Walburga von Waldburg zu Zeil und Trauchburg is married to Baron Carl von Lerchenfeld, first cousin of the aforementioned brothers Counts Christoph and Alexander Schenk von Stauffenberg.
The Lerchenfelds are direct descendants of Lord Thomas Howard, Earl of Suffolk, son of Thomas Howard, 4th Duke of Norfolk, by his second marriage.
St Philip Howard, Earl of Arundel was the only son of the latter's first marriage.
Earl of Arundel and martyr for the Catholic Faith.
Countess von Stauffenberg (born von Lerchenfeld) was a kinswoman of the great English saint.
Thomas Howard, 4th Duke of Norfolk, though a Protestant, was executed for his alleged involvement in the Ridolfi plot, for proposing marriage to Mary I, Queen of Scots (and de jure II of England and Ireland). The Royal Pedigree of the Duke of Norfolk is well attested.
The Lerchenfelds also have impeccable Scottish pedigree, from the Royal Stewarts (via King Robert II of Scotland and his wife, Euphemia, daughter of the Earl of Ross) and from very many Scottish noble families.
Count Claus Stauffenberg's granddaughter, Countess Sophie Schenk von Stauffenberg is married to Baron Marcus Berchtolsheim, the Chancellor of the Duke of Bavaria and himself a descendant of the Royal Stuarts, through the brother of the Royal nephews, and Cavaliers during the English Civil War, "Prince Rupert" and "Prince Maurice of the Rhine", Edward, Count Palatine (Pfalzgraf) of Simmern, who became a Catholic on his marriage to Anna Gonzaga, heiress of the Gonzaga Dukes of Mantua.
His grandson, Count Hans Caspar Schenk von Stauffenberg is married to Gräfin Josefa von Waldburg-Zeil-Hohenems, a Habsburg, Bourbon and Royal Stuart (Charles I) descendant.
It is as if the hand of God were on Stauffenberg ordaining him to make the attempt on the life of the Nazi Antichrist.
On this happy day doubtless the newly-weds could hardly have foreseen then that he would be the one man in Germany who would get closest to ridding the world of the leading Nazi Antichrist.
