Richard Sandbach (1130 – ????) was the 32nd great-grandfather of Cometan, classified as one of Cometan’s medieval paternal ancestors in the Taylor family line. Little is known of Richard’s life except for that he was the father of Richard Sandbach (1150 – 1225) who connects him to the Cometanic ancestry.
In Cometanic ancestry, Richard Sandbach is categorised as part of the 34th generation retrograde, and because he was born before 1453, he is classified as a medieval ancestor of Cometan, a title that is rarely bestowed. He is one of the earliest, if not the earliest, known ancestors of Cometan.
