Henry Moon (also spelt as Moone; February 1587 – February 3, 1630) was the 11th great-grandmother of Cometan, classified as one of Cometan’s distant maternal ancestors in the Prescott family line. Born in Hollowforth, Newsham, Lancashire, Henry was the son of the clockmaker Sir Robert Moone and Lady Alice Dilworth and was the husband of Ann Raby (1584 – 1670) and the father of Robert Moon (1617 – 1691). The marriage of Henry Moon and Ann Raby took place on 1st October 1609 in Hollowforth, Newsham.
In Cometanic ancestry, Henry is classified as part of the 13th generation retrograde, thus categorising him as a distant ancestor of Cometan.
