I had a look at these Aubreys just because of the possibility of a link to the baronetical family (which doesn't appear to exist), but some notes anyway:
Thomas Dixon Rodbard Aubrey B.A. (Oxon.), L.M.S.S.A., Squadron Leader, R.A.F. s. of Thomas Aubrey (1876-1945), of Westover House, formerly of Woodbine Cottage, Bitton, Glos., formerly of Isleham, Cambs., G.P. (at Bitton 1905-45), surgeon and (m. 1900) Maria (Mia) Isobel (1872-1946), dau. of Richard Castle, of Westbury-on-Trym, Bristol, Glos., hosier and outfitter.
Thomas Aubrey eldest s. of Thomas Aubrey (1833-1914), of 34, Oakfield Road, Clifton, Bristol, formerly of Walcot, Bath, Somerset, formerly of Catherine Street, Alderbury, Salisbury, and of Stratford-sub-Castle, Wilts., veterinary surgeon and (m. [1876?]) Kate, dau. of [- Broad?], of Trowbridge, Wilts. Two of their sons, Harold Percivall and Francis Leonard, were dental surgeons.
Thomas Aubrey eldest s. of another Thomas Aubrey (1811-1870), of Catherine Street, Alderbury, formerly of Milford Street, Salisbury, farrier, blacksmith emp. 1 man and (m. 1832) Jane (1813-), dau. of - Dixon, of East Harnham, Wilts. Another of their sons, Benjamin Biles Aubrey, also became a veterinary surgeon. Two daughters were Ellen Henrietta Dixon Aubrey and Emily Dixon Aubrey, that middle name not seeming to reappear until the aforementioned T. D. R. Aubrey.
The eldest Thomas Aubrey appears in the 1841 census alongside an Elizabeth Audrey, aged 70, presumably his mother.
