Question:

Where does the last name Mann come from? Is it Irish? German?

Best Answer - Chosen by Asker: Mann
This interesting name has two possible origins. The first being
from the Old German "mann" meaning man, probably used as a nickname
for a fierce or strong person or for a man contrasted with a boy
for some reason. Alternatively the source could be from the pre 7th
Century English personal name "Mann", man, which was still in use
in the 12th Century. Although the exact sense is not always clear,
a common meaning is servant, but it also may correspond to such a
phrase as "homo Bainardi", the man of Bainard, one who owed him
feudal service. One Robert Mann, married Avis Hankel in 1577 at St.
George the Martyr, Canterbury.

The Coat of Arms granted to the family has the blazon of a gold
shield, a chevron ermines between three black lion's rampant. The
crest being a gold tower issuant from the top of five tilting
spears proper, with the motto; Virtus vincet invidiam. The first
recorded spelling of the family name is shown to be that of
Hugo filius Man, which was dated
1188, in the Pipe Rolls of Lincolnshire, during the reign of
King Henry 11, known as 'The Builder of Churches', 1154 - 1189.
