The service of the Land family is open to debate. I have three references to service:
Edward Land: Albemarle Co., VA - Capt. Robert McKenzie's company.
Thomas Land: Rev War soldier - Capt. Roberts' Co. - 1776
John Land: His son, Thomas, stated in the pension application of Daniel Isbell, that his father [John] was a soldier for Virginia during the war. Both his father and Isbell had mentioned the other's service.
It is possible that the trio above covers three generations of service, grandfather, father, son.
