Johann I von Lichtenberg the Elder
Johann I von Lichtenberg, called the Elder (first recorded 1281, died 22 August 1315), was lord of Lichtenberg and Vogt in Alsace, leading the younger branch created by the family partition of 1271. The second son of Ludwig II and Elisabeth of Baden, he inherited that line's estates and married Adelaide of Werdenberg.
When the elder branch's Conrad I died in 1294, Johann became guardian of Conrad's young son Johann II. His uncle Konrad III was bishop of Strasbourg.
