My grandmother was Georgianna Gladding, that married my grandfather, Philip Newitt in 1915 in Ely, NV. (she was originally from Ashtabula, OH). I have a Nevada published history that tells of how the Gladding name is derived from the Osbert family, that took the name of the English estate, 'Gladesfer" before 1660. An ancestor of the Osbert family was killed in the battle of Hastings (1066).
