Cosman Spelling Variations

Until quite recently, the English language has lacked a definite system of spelling rules. Consequently, Anglo-Saxon surnames are characterized by a multitude of spelling variations. Changes in Anglo-Saxon names were influenced by the evolution of the English language, as it incorporated elements of French, Latin, and other languages. Although Medieval scribes and church officials recorded names as they sounded, so it is common to find one person referred to by several different spellings of his surname, even the most literate people varied the spelling of their own names. Variations of the name Cosman include Castleman, Casselman, Cassman, Cassellman and others.
