Patronymica Britannica (1860)

HAYMAN. Hay signifies both a hedge and what it encloses ; hence Hayman and Hayer probably sometimes mean the same as Haj'ward, which see. But the Irish family of Hayman or Heyman deduce their pedigree from Rollo, the founder of Normandy, through the Crevecoeurs, one of whom, Haimou de C, had a sou Robert, who assumed his father's laptismal name as a surname, which he transmitted to his posterity.
