Kirchberg
Kirchberg was a Swabian county south of Ulm, with its seat at Oberkirchberg and lands on both sides of the Iller. Around 1250 its counts split into three branches.
When Count William died in 1366, much of his inheritance passed through his daughter to the Matsch family. The Wullenstetten branch recovered the county as a pledge in 1390. Its last cousins sold their halves to Duke George of Bavaria in 1481 and 1498; Maximilian I pledged the lordship to the Fugger in 1507. The Kirchberg family died out in 1510.
