General Notes

Rel: Lutheran
Note: Born name is Susannah Schlern, anglicized to Sehler. Died in New Market, Shenandoah County, Virginia.
Susanna Sehler..n (the `n` for German female ending) was originally thought to be Schler..n as transcribed from an old paper that was hard to read found at St. James Lutheran Church in Greenville, Tennessee. Schler..n was the transcription made from this newspaper and is mentioned in Book 3 of "The Roush Family in America". No ancestry on this surname could be found. Much of the John Adam information was taken from the 4 Vol. set titled "The Roush Family in America" Volume 1-3 Written 1928, 1942, and 1963 by Rev. Lester Leroy Roush. Volume 4 written in 1979 by Walden F. Roush. Volume 4 of the set gives credit for the pre-American research as being done by Dr. Walter Roush, an educator and resident of Germany. Further reading should include "Thirty Thousand Names" by Daniel Rupp. German translators suggest the Americanized version of the name Sehler could very well be "Sellers".

The Shenandoah Valley Roushes, From: A history of Shenandoah County, Virginia, by John W. Wayland. Strasburg, Va. : Shenandoah Publishing House, 1927. pp. 721-722. Contributed by Rev. L. L. Roush, Rutland, Ohio
John Roush (Rausch) and wife Susannah were among the early settlers in Shenandoah County. About 1738 they emigrated from the Palatinate, a small country on either side of the Rhine, near Alsace-Lorraine. The causes for their coming to America were religious persecutions, devastating wars, and political oppression, but most especially the former. Devout Protestants they were from the beginning and more ardently so later when they espoused the pietistic movement, or "religion of the heart", which even occasioned greater persecution from their Catholic neighbors. First in Pennsylvania and later in the Shenandoah Valley they became active as land owners, tanners, builders of churches, etc.
John Roush, Sen., took up a tract of 400 acres of land on Mill Creek, a little west of Mount Jackson, and from time to time added to and sold until there are more than thirty land transactions recorded in his name or some of his sons.
This man and woman were the progenitors of a large family the descent of whom is now to be found in almost every state of the Union. They are specially numerous in Mason County, West Virginia, Adams, Highland, Meigs and Gallia counties, Ohio, to which they emigrated from the Valley in 1795-1800.
They were active in the Lutheran faith in these early days, and John Roush, Sr., lies buried in the old cemetery at Pine Church. The leaning grave stone shows him to have been born 1711 and died 1786. The family was largely responsible for the founding of Old Solomon's church near Forestville in 1793, a son, Henry Roush, having deeded 2 1/2 acres of land now occupied by the church and cemetery. For this sort of things they have made themselves prominent in the communities to which they later went.
Having had personal acquaintance with George Washington and Peter Muhlenberg, their ten sons engaged in the war of Independence, some of them remaining in the service until its close, George and Jonas being with Washington when Cornwallis surrendered. Jacob was with General Andrew Lewis in the terrible battle of Point Pleasant, West Virginia, October 10, 1774. By nature they have been a patriotic, home-loving people and have served their country in every conflict from the French and Indian War to the late World War.
The children of this family whose descent is now being traced are as follows: Philip, 1741-1820, buried in Cheshire, Gallia Co., Ohio. John, Jr. (Captain in Revolution), 1743-1816, purchased 6,000 A. on the Ohio river in Mason Co., W. Va., to which he moved 1798; left no descent. Jacob, 174?-1830, had shares in the Ohio Land Co.; came to Gallia Co., O. about 1796; buried there. Henry, 1749-1830, came to Mason Co., W. Va., 1798, and to Letart, Meigs Co., O. 1800,
where he is buried. Daniel seems never to have left the Valley. He left no offspring. George, 1761-1850, came with his brother, Captain John, 1798; later to Meigs Co., O., buried in Racine, O. The descent of his thirteen children are numerous in this vicinity. Jonas, 1763-1850, came to Mason County, 1800, where his descent is numerous, buried in Nease Settlement Cemetery. Mary Magdalene, married Lewis Zirkle, whose descent is still in the Valley in the vicinity of New Market. Three of Philip's sons were of the company that formed the third permanent settlement of the Northwest Territory, in Sprigg Township, Adams Co., O. The families of George and Jonas founded at New Haven, W. Va., the first church west of the Alleghany mountains.
