The many Renick family trees that are displayed on the web almost all report that Felix Seymour (b. 1725 Ireland, d. 1798 Hardy County, [West] Virginia)was married to a Margaret Renick. These trees, however, are divided sharply on two important matters: (1) Margaret Renick's parents, and (2) her date of death. Margaret's father is variously claimed to be William, George, or Thomas Renick. Some trees assert she died in 1778 while others tend to favor 1798.
It is possible that there were multiple Margaret Renicks who lived at about the same time and place. The Renicks of the 18th and 19th century were notorious for favoring a rather limited band of given names. It is equally possible, however, that the web has resulted in proliferation of reports that are simply incorrect.
I'm curious whether anyone who has studied the Renick family has uncovered solid primary source records that might illuminate this matter. If I recall correctly, Shuck's transcription of Hampshire and Hardy County records contains only one index entry for a Margaret Renick who almost certainly was born decades after the wife of Felix Seymour.
