John Moorby (September 1688 – ????) was the 8th great-grandfather of Cometan, classified as one of Cometan’s distant paternal ancestors in the Hardacre family line. Born in Skipton in Yorkshire, John married Elizabeth Gumersall and they had at least one son together named Thomas Moorby (1725 – 1803). The details of both John’s death and the identities of his parents remain unknown.
In Cometanic ancestry, John is categorised as part of the 10th generation retrograde, classifying him as a distant ancestor of Cometan.
