Meaning & History
Either (i) from a medieval nickname for someone who crossed marshy moorland (e.g. who lived on the opposite side of a moor, or who knew the safe paths across it); or (ii) perhaps from an alteration of Passemer, literally "cross-sea", an Anglo-Norman nickname for a seafarer. Bearers include Australian artist John Passmore (1904-1984) and British artist Victor Passmore (1908-1998).
