How interesting, thank you for all your hard work! I'm related to the Busharts through robert Newton's wife Mary Jane Hardin (my great great aunt)and through John B.'s wife Rachel Cayce (also a great-great-aunt.) Rachel was married to John B.; Ellen Tennessee Kindred was first married to Rachel Cayce's brother Hardy. When both the Cayces' died, they then married each other.
Thank you for the wonderful info to add to my family history.
