Mary Duncan was a 4th great grandmother of mine.  She was born about 1786 in South Carolina.  Her father was Samuel Duncan.  Samuel moved the family to Miami County, Ohio where Mary met and married Isaiah Pemberton.  With Isaiah she had one daughter whose name is currently unknown.  Sometime around 1815, Mary then married Henry Neal and they had four children–John, Thomas, an unnamed girl and an unnamed boy.  Henry died sometime in the late 1820s and Mary married once again, this time to John Coppock.  Mary and John had one son, Benjamin, who is my 3rd great grandfather.

John Coppock toyed with the idea of moving to Indiana and went so far as to scout things out in 1836.  He changed his mind, though, and returned to Ohio.  His stepson John Neal, however, stayed and settled in Clay County, living with a brother-in-law.  It’s not clear if that brother-in-law is married to his (unnamed) sister or his wife Elizabeth’s brother.  It’s likely that Thomas Neal soon followed his brother and settled there as well.

John Coppock died at the age of 77 in Miami County, Ohio.  This was probably around 1842 when it is reported that Benjamin moved to Clay County and lived with Thomas and his family.  It’s likely that Mary came with him since she is reported to be living with Thomas in both 1850 and 1860.  According to Benjamin’s biography, Mary lived to be 81 years old.  Combining this with her approximate age from census records, Mary died around 1867 in Clay County.
