The Stuell (Steull, Still) Family of Klafeld and Seelbach
In what follows, "A" will be used for Boettger's "Auf den Huetten," a history of Weidenau; and "K" for Boettger and Busch, "Geschichte der Gemeinde Klafeld-Geisweid", a history of the Klafeld township.
The name Stuell or Steull seems to have originated in the District of Burbach in the Free Ground, just south of Nassau-Siegen, where it appears as early as the late 1400's. It appears in Nassau-Siegen in various places in the 16th century (K 213). There are various spellings of the name in the early records. It is always spelled Still at the present time. Hans Stuell of Weidenau, and Hans and Henrich Stuell of the adjacent township of Klafeld, all appear in the records 1563-66, and were probably related. Anna Stuell, wife of Johannes Otterbach of Trupbach, was descended from Hans Stuell of Klafeld, but we shall deal briefly first with the family of Hans Stuell of Weidenau and his brother, Kurt Stuell of Eiserfeld. These two brothers, along with Hans's wife, Kunigund, joined in a deed in 1559, selling a meadow that belonged to them at Buschgotthardshuetten in the Weidenau township. Hans Stuell was probably born about 1525, as he was young enough to be in the militia at Weidenau in 1572. His wife, Kunigund, may have been a Zinner. In the records of Weidenau, 1563-1583, he is called both Hans Stuell and Hans Schneider, and last appears there in 1583. He seems to have been the father of Johann Trupback of Weidenau, who was also called Schneider. In 1597 Hermann Schneider of Trupback, son of Johann Schneider of Weidenau, decd., was appointed an associated justice of the Hain Court, and continued to live at Trupbach until his death in 1637. We have indicated that the Otterbach family of Trupback may have been descended from him. In Weidenau the descendants of Johann Trupback-Schnider were usually called Trupbach, but occasionally Schneider (A 34-35, also 44-45). Thus the name Stuell seems to have died out at Weidenau and been replaced by Schneider at Trupbach, and Trupbach at Weidenau.
Kurt Stuell of Eiserfeld, who appears in 1559 with his brother Hans of Weidenau, was probably the father of Henrich Stuell of Niederschelden, a village very close to Eiserfeld, who appears there in the tax list of 1583. Henrich, in turn, was probably the father of Nolden (i.e., Arnold) and Johann Stuell, who appears at Niederschelden in 1599. Later descendants of these Stuells were probably the following: (1) Theiss Stuell and wife Gertrud of Eiserfeld, who had the following children christened at Siegen: Johannes in 1629, Johann in 1634, Johannes in 1637, and Anna Catherina in 1639; (2) Hermann Stuell and wife Magdalena of Eiserfeld, who had, Anthonius, chr. 1639, Johannes chr. 1641, Christian chr. 1644, and Anna chr. 1647; and (3) Jost Stuell of Niederschelden and wife Anna, who had: Gela chr. 1639, Johannes chr. 1643, Elsa chr. 1647, and Maria chr. 1651.
