I was delighted to hear of your interest in the Orby Hunter ancestral line.
As far as I am aware Robert and Elizabeth had four children. but I cannot be sure of the order in which they were born so treat the dates as a guide only. Some of the children were probabloy born in Jamaica. or possably at Waverley Abbey in Surrey
1. Katherine Hunter borfn circa 1709. Maried Willian Sloper 1737.
2. Henrietta Hunter, born circa 1710 died 1757.
3. Charlotte Hunter born circa 1711.
4. Thomas Orby Hunter born circa 1714. died b20 Oct 1769.
I would be very interested to learn if you have any additional information.
