E. G. Strobel was not a descendant of Johann Casper Strobel.
E. G. Strobel was the son of John G. Strobel who petitioned the court in Barnwell to grant him citizenship in 1853. John G. Strobel was born in Saxony, Germany and arrived in the US in 1840 at the age of 13. He married a Louisa Neely or Neeley. There were several sons by John and Louisa.
One son, John Robert Strobel, is buried in the Ott Cemetery and may have been misidentified as being a member of the more familiar Strobel family of Colleton/Orangeburg area.
Daniel Strobel, who married Elizabeth Aberly, was a descendant of Johann Casper Strobel of Lampertheim, Germany. It would appear that one of his sons, Daniel Strobel, Jr. was married previous to that of Annie Murray. By this first marriage there were the following sons: William Strobel who married Martha West, widow of D. R. Bowman; Jacob G. Strobel who married Arabelle unknown; Daniel V. Strobel who married Susan Catherine Pendarvis; John R. Strobel who may have been the spouse of Mary E. Wimberly. There was another possible son, David L. Strobel who married a Frances unknown. Jacob and Daniel both settled near Newnansville, Alachua, Florida, before 1850. William and John R. Strobel remained in SC.
In about 1860 it is known that David Gavin's brother, Charles Gavin was also living in the Newnansville area and is enumerated in the Alachua County census as a near neighbor to the above Strobels. By 1870, Charles was widowed and his only daughter had moved back to SC.
Charles would later remove himself to South America.
David and Charles Gavin and the sons of Daniel Strobel, Jr. mentioned above were related through the Aberly family.
The brother of Daniel Strobel, who married Elizabeth Aberly, Albert Strobel, married Elizabeth Bowman, daughter of Jacob Bowman and Catherine Carn. Catherine was a descendant of Lewis J. Carn and Catherina Elizabeth Strobel. Catherina was the brother of Casper Strobel, father of Albert and Daniel Strobel.
Albert Strobel and Elizabeth Bowman had at least three children: Anna Elizabeth Strobel, who married John R. Moorer, Jr.; David Strobel, who married Sarah Spell; and a third child who many feel is the John Strobel who died in 1830's and whose widow married Major Abner Jackson who migrated to Texas. It is said that Abner Jackson raised the son of John Strobel, Lewis M. Strobel. Lewis in turn named one of his sons, Abner Strobel, all of Brazos, Texas.
There is not total agreement over this, however.
Anna Elizabeth Strobel, who married John R. Moorer, Jr., had several children. One daughter, Ann C. Moorer, married Simeon Hussey. One of the children of this marriage, John M. Hussey, in turn, married Mary Ann C. Strobel, his cousin, the daughter of David Strobel and Sarah Spell.
John M. Hussey's brother, Simeon Albert Hussey, had a daughter, Ada Hussey. Ada's daughter, Mattie Knight, married John R. Strobel, Jr, Ada being the wife of Willis Townsend Knight, the son of Samuel Knight and Mary Patrick. John R. Strobel, Jr. was the son of John R. Strobel, who was the son of Daniel Strobel, Jr.
John R. Strobel's brother, William W. Strobel, married Fannie Knight, granddaughter of Samuel Knight, cousin of Mattie Knight.
