Much of the information regarding Robert Sibley was tekn by James Scarborough Sibley, author of The Sibley Family in America 1629-1972, was taken from Census Records and the Diary of John Osborne, a resident of Mecklenburg County, North Carolina and a neighbor of John Sibley.
It appears that Robert Sibley was born in Mecklenburg but moved toHalifax County Virginia, where his grandfather lived, around 1754. In 1755, he married Jerusha Chandler, whose family appears to have been as numerous there at the time as the Sibleys were. All of Robert and Jerusha's chil;dren were born in Halifax County Virginia.
Around 1782, Robert and Jerusha moved to Charlotte County Virginia.
Around 1802, Robert moved back to Mecklenburg, probably to be near his ailing father who died shortly thereafter. In 1804, Robert sold 200 Acres of Land in Mecklenburg County to his son Elijah. Robert's Will was probated in Mecklenburg County in 1809.
The Diary kept by Robert's father's neighbor, John Osborne, indicates that (1) John was Robert's father, (2) Robert's brother was Elijah, (3) Robert lived in Virginia and came to North Carolina to "visit his people in Mecklenburg," and (4) he owned, bought and sold slaves.
