I, too, am a descendant of James Stell Coberly through his son Martin.
George Coberly, a son of James Stell and Mary (Poffenberger) Coberly, was born 20 Feb 1788.According to my records he had three wives.He married 1st Sarah Bean on 26 Mar 1811; 2nd Matilda Lewis 13 Oct 1816.Both marriages were in Hardy county, (now West) VA.He married 3rd Mary Ann Mathews. He died 11 Jul 1855 Hancock co., IL.
There is a wonderful book written by John Bradley Arthaud entitled "A Coberley/Coberly/Cuberley Genealogy 1690-1985" which contains a wealth of information on this family.Dr. Arthaud is a wonderful researcher who has been careful to document his facts.I'm guessing it is probably available in most large genealogical libraries or through inter-library loan.
