The following is an excerpt from the book "Ancestry and Descendants of the Nassau-Siegen Immigrants to Virginia 1714-1750" by B. C. Holtsclaw on page 488. At this time, this is all I know about this line of the family.
Goebel (Gebel) Beer of Seelbach was the grandfather of Ehla (Beer) Stuell. In 1563 he was lessee of the Wildenburg farm, one of the four farms of which the settlement of Seelbach consisted at that time, and was still living at Seelbach in 1583, the only Beer there. Goebel Beer was probably born ca. 1535-40, and may have been a brother of Johann Beer, who appears in 1566 in Siegen as a member of the Miner's Guild. Guebel Beer was dead before 1599, in which year two Beers, apparently his sons, were living in the Siegen judicial district, Jacob Beer in Seelbach and Johann Beer in Klafeld.
Jacob Beer of Seelbach, son of Goebel Beer and father of Ehla Stuell, was born about 1565-70, and died at Seelbach after 1629, when his daughter, Anna, was godmother of Anna, daughter of Jost and Ehla Stuell. In 1624 he was Heimberger, or chief administrative officer, of Seelbach. In addition to Ehla and Anna, Gerlach Beer, godfather of Gerlach Stuell in 1631, also seems to have been one of Jacob Beer's children. Another son may have been Johannes Beer, who was a member of the militia at Birlenbach (in the Klafeld township) in 1624, though this Johannes could have been a son of Johann Beer of 1599 in Klafeld. This Johannes Beer of Birlenbach was the godfather of Johannes Fischbach, father of Philip Fishback, the 1714 immigrant, which may indicate that Johannes Fischbach's mother, Liess or Elizabeth, was a Beer.
