Elfingen

While Alamanni graves have been discovered in the municipality and it was the seat of a fief holder from Murbach Abbey in the 7th Century, Elfingen is first mentioned in 1245 as Eolfingen. When the Abbey sold their holdings in Aargau to the Habsburg in 1291, Elfingen was included. It came under the authority of Bern starting in 1460 and was part of the bailiwick Schenkenberg.
The Catholic parish church, was consecrated in 1323 to St. Leodegar. However the parish seat moved in the 16th Century to Bözen. The new parish included Bözen, Effingen, Zeihen , Linn and Densbüren . The parsonage remained in Elfingen until 1824, when it moved to Bözen. By 1720 the village had its own school.
