According to my notes, Zelpha Murphy (b. abt 1810) married Matthew Jinkins and is my 4th great grandmother.Her parents were John and Sarah Murphy.Another 4th great grandmother of mine, Sarah Murphy (b abt. 1797), married William Allard.The two are either sisters or first cousins, depending on whether Sarah's father was John or Alexander.(John had a son Alexander as well.)Both Sarah and Zelpha gave their birth state as South Carolina in the 1850 IL census, though I believe they may have lived for a time in Tenn.
William Allard's father, David, and grandfather, Hardy, settled in Illinois before 1816.It seems reasonable that William was married in Johnson or Pope County.I would love to have the record.
Despite the fact that my grandfather has Murphy lines on both his maternal and paternal sides, he knows of no family legend that they were Native American.It sounds like you have information I would love to see.I'll contact you offline.
