Roseman
A surname of uncertain but likely continental origin, probably built from the Germanic personal-name element found in forms like Rosemond and Rosamund.
The #8,297 most common surname in the United States (2010 Census) — about 1 in every 77,322 Americans shares it.
Etymology
The name is usually explained as containing the Germanic name element rose- or hros-, though the exact source form is not certain. Weekley notes that Roseman belongs with Rosamond and is of continental origin, which points to a surname derived from an old personal name rather than from the flower rose. In practice, it may have arisen as an altered or shortened form of a Continental given name or nickname that later became hereditary as a surname.
History
The surname is found in English-language records by the 18th century, and it also appears in later American usage. Because the old sources treat it only briefly and do not agree on a precise derivation, its history is best described as one of continental import into English rather than a clearly local English occupational or place-name surname. Modern bearers are most likely descended from families whose name was already established in Britain or North America before surname spellings stabilized.
