Gliddon is a name of ancient Anglo-Saxon origin and comes from the family once having lived in the region of Gledhill in the West Riding of Yorkshire. The name is a habitational name from the Old English gleoda which means "kite" and hyll which means "hill." 
The surname Gliddon was first found in Yorkshire near Halifax where they held a family seat as Lords of the manor of Gledhill from very ancient times. Barkisland in the West Riding of Yorkshire was home to another branch of the family but has since been lost. "Barkisland Hall, the ancient seat of the Gledhill family, is a stately mansion in the old English style of domestic architecture, and has long been the property of the Bolds of Bold Hall, Lancashire. The grammar school here, an ancient structure, was endowed in 1657 with £200 by Mrs. Sarah Gledhill"

Sound was what guided spelling in the essentially pre-literate Middle Ages, so one person's name was often recorded under several variations during a single lifetime. Also, before the advent of the printing press and the first dictionaries, the English language was not standardized. Therefore, spelling variations were common, even among the names of the most literate people. Known variations of the Gliddon family name include Gledall, Gledhill, Gladhill, Gladhall, Glanville and others.
For political, religious, and economic reasons, thousands of English families boarded ships for Ireland, Canada, the America colonies, and many of smaller tropical colonies in the hope of finding better lives abroad. Although the passage on the cramped, dank ships caused many to arrive in the New World diseased and starving, those families that survived the trip often went on to make valuable contributions to those new societies to which they arrived. Early immigrants bearing the Gliddon surname or a spelling variation of the name include:
