Anna Ottilie Patterson (31 January 1932 – 20 June 2011) was a Northern Irish blues singer best known for her performances and recordings with the Chris Barber Jazz Band in the late 1950s and early 1960s.

[7] In 1949, Patterson went to study art at Belfast College of Technology where a fellow student introduced her to the music of Bessie Smith, Jelly Roll Morton and Meade Lux Lewis.

[8] In 1951 she began singing with Jimmy Compton's Jazz Band, and in August 1952 she formed the Muskrat Ramblers with Al Watt and Derek Martin.

[5] In the summer of 1954, while holidaying in London, Patterson met Beryl Bryden, who introduced her to the Chris Barber Jazz Band.

Patterson would thus sing with, for example, Muddy Waters, Sonny Boy Williamson, Big Bill Broonzy, and Sister Rosetta Tharpe.

From approximately 1963 she began to suffer throat problems and mental health difficulties and ceased to appear or record regularly with Chris Barber, officially retiring from the band in 1973.

[1] During this period she recorded some non-jazz/blues material such as settings of Shakespeare (with Chris Barber) and in 1969 issued a solo LP 3000 years with Ottilie which is now much sought after by collectors.

[13] In early 1980 she began singing with the Chris Barber Band again in a series of lucrative concerts around London,[14] which were recorded for the LP, Madame Blues and Doctor Jazz (1984).

Her gravestone, which is marked Ottilia Anna Barber, is immediately by the left hand wall adjacent to the car park.
