Aymon II von Turn

Aymon II von Turn, also spelled Aymo (c. 1240–1276), was a baron of the leading Valais noble house seated at the Gestelnburg above Niedergesteln, and the son of Gerold I. On his father's death he inherited the vicedominatus, the bishop's temporal advocacy, of Conthey.

His sister Nantelma, widow of Rudolf von Raron, brought the family her late husband's estates at St. Niklaus and Zermatt. Aymon headed the house from 1265 until his death in 1276, when his son Peter II succeeded him.
