Ann Moon (also spelt as Moone; née Raby; 1584 – October 1670) was the 11th great-grandmother of Cometan, classified as one of Cometan’s distant maternal ancestors in the Prescott family line. Born in Hollowforth, Woodplumpton, Ann was the daughter of William Morecroft and Anne Walker and the wife of Henry Moon (1587 – 1630). Ann was buried on 27th October 1670 in Woodplumpton, Lancashire.
In Cometanic ancestry, Ann is classified as part of the 13th generation retrograde, thus categorising her as a distant ancestor of Cometan.
