Sir William de Houghton, Knight (1366 – c.1422) was the 22nd great-grandfather of Cometan, classified as one of Cometan’s medieval paternal ancestors in the Taylor family line. Born in Preston, Lancashire, Sir William was the husband of Alicia de Houghton and is also known to have been the father of Isabel Houghton. He was also the son of Sir Richard de Hoghton, Knight and Joan de Hoghton. The details surrounding Isabel’s death remain unknown except for that he died in Preston, Lancashire.
In Cometanic ancestry, Sir William is categorised as part of the 24th generation retrograde, and because he was born before 1453, he is classified as a medieval ancestor of Cometan, a title that is rarely bestowed.
