I had a look at the Pritchard-Barretts yesterday, just because the name appealed to me I suppose!-
Christopher P.-B. second son of Stanley Pritchard-Barrett (1900-1961), of Tiggins House, Kelsale, Saxmundham, Suffolk, Lt, General List (WWII), Flying Officer, R.A.F. (-1929), by his wife (m. 1926) Winifred Mary (1901-1976), dau. of Doyley Scott Ransom, of Nottingham, solicitor [as a widow, she was of Fairfield House, South Saxmundham]. Stanley P.-B.'s elder son, (John) David (1928-2006; see death notice here-
http://announcements.telegraph.co.uk/deaths/16208/pritchard-barrett), was of Rookery Farm, Kelsale, C.E.O. of the Greenall's and Whitbread breweries, and director of a silviculture and forestry company; he had previously worked for IBM in the U.S.. By his wife Joannie, dau. of Col Frank J. MacNees, U.S.A.F., Commander of Donaldson Air Force Base, Greenville, S.C., U.S.A., he had three sons and a daughter.
Stanley P.-B. second son of John Nightingale Cooke Pritchard (1869-1900; later Pritchard-Barrett, adding his stepfather's surname, see below; usage seems to have been, as is so often the case, inconsistent- his marriage record indicates 'John Pritchard' to be forenames and 'Barrett' the surname, with 'Pritchard' coming to be part of the surname again later), of Sydenham, Kent, a stage actor. He had married, in 1893, Clara Lydia, dau. of Albert John Hills, of Lewisham [she m. 2nd, 1902, Lt-Col Sir Robert Benyon Nevill Gunter, 2nd Bt, of the Yorkshire Regiment]. The elder son, John Oscar (1896-1915) was killed whilst serving as a Lieutenant in the Green Howards.
J. N. C. Pritchard was son of John Pritchard (1830-1868), of Nursery Cottage, Town Moor, Newcastle upon Tyne, stage actor ('leading tragedian of the northern circuit'), and his wife (m. 1867), Eliza, dau. of Robert Dorling, of Bethnal Green, formerly of Shoreditch, tallow chandler [she m. 2nd, 1873, Oscar Harmon Barrett, composer and pantomime producer at the Crystal Palace and in the West End]. John Pritchard's father was another John Pritchard.
Information on the earlier generations of the family from this site
https://northdoor37.com/blogs/news/5955091-the-young-widows by an apparent relation of Oscar Barrett- a now overlooked but at the time apparently fairly influential figure rivalling Sir Augustus Harris- about whom the site owner seems to have written a(n) (e-)book.
