From the Latin name Ursula, a diminutive of ursa ‘(she-)bear’. This was the name of a 4th-century saint martyred at Cologne with a number of companions, traditionally said to have been eleven thousand, but more probably just eleven, the exaggeration being due to a misreading of a diacritic mark in an early manuscript. This name was moderately popular in the 16th century, but its use in the English-speaking world today is selective. A more recent influence has been the film actress Ursula Andress (b. 1936 in Switzerland).
English and Scottish: habitational name from any of the numerous and widespread places so called. The majority of these are named with Old English middel ‘middle’ + tūn ‘enclosure’, ‘settlement’; a smaller group, with examples in Cumbria, Kent, Northamptonshire, Northumbria, Nottinghamshire, and Staffordshire, have as their first element Old English mylen ‘mill’.
