Johannes was living at Aga in 1519 and paid the highest tax in Hardanger in 1521 (40 marks). According to Audun Dybdahl, author of the Rissa Bygdebok Bd. I, and also author of Fosens Historie, "Some days ago I published a tax list from 1520 that cover a great part of the western Norway and Trøndelag. A part of that list that I did not publish, shows that Johannes at Aga was one of the richest men in Hardanger at that time."
Johannes married Gyrid Torgilsdotter Aga, daughter of Torgils Vikingsson Aga and Gudrun Ormsdotter Lydvo, about 1540 in Norway. (Gyrid Torgilsdotter Aga was born about 1475 in Aga, Ullensvang, Hordaland, Norway.)
