There are few sources proving the dates on which George Cockburn’s children were born, but one indicator is his 1834 last will and testament, written and probated in Franklin County, Georgia. James and Malissa are singled out in the will (and therefore listed out of order) because they were given most of their father’s property, but the rest of George’s children were given one dollar, and were apparently listed in order of birth: Archibald Cockburn, Jerusia Blackwell, George Cockburn, Rachel, John Cockburn, Josiah Cockburn, Russel Cockburn, Jeremiah Cockburn, Sarah Cockburn, and Clark Cockburn. Although James was listed out of order, his 1850 census record confirms that he was born circa 1778 in Virginia. From this information, we can assume that Archibald, James and George were among George’s first sons and that Elizabeth Snyder was probably their mother.
