Not sure about proving it, though

.
From the headstone inscription Thomas Kerr & Jannet Standert were George’s parents. Thomas died in Esbie January 26 1764 age 75. The John I found died Old Esbie August 18 1777. So, Thomas would have been born 1689 and John born 1705 – 16 years difference.
George KERR and Christina Burgess first born was a son - John b. 1770. Their daughter Janet was born at Old Esbie 1771. They also had a son James b. 1773. The names seem to follow through.
