The late Mrs Moubray's grandson, James MOUBRAY, and his wife, née Eva-Maria STEGEMANN (engaged 2019 - see Richard's posting at
https://groups.google.com/g/peerage-news/c/Ep7COjQyFe8/m/iiBwbse5GgAJ), would appear to have two daughters, Lilli May C MOUBRAY (birth registered Q3 2020) and Maxi Maria C MOUBRAY (birth registered Q4 2022); both births were registered in Lambeth, and the mother's maiden name is Stegemann in each case.
Mrs Moubray's parents were second cousins. Her maternal grandfather, Henry ("Harry") WHITWORTH (5 IV 1870 - 30 X 1930) was the son of Spedding WHITWORTH (1832 - 22 VI 1899), the founder of Whitworth, Son & Nephew, brewers, of Wath on Dearne, West Riding of Yorkshire. Her maternal grandfather, Maj Charles Warwick WHITWORTH, OBE, TD (12 I 1878 - 12 XII 1954), was Spedding Whitworth's nephew. Her maternal grandmother, née Cicely Sarah DARLEY (1883 - 7 IV 1920), was a member of another brewing family, that of W M Darley, of Thorne, also in the West Riding of Yorkshire.
Mrs Moubray's husband was of that family, of Broonlands, formerly of Naemoor, which, per Burke's Family Index, last appeared in Burke's Landed Gentry (LG) in the 1952 edition. He was the son of Col John MOUBRAY, DSO (8 V 1898 - 19 VIII 1951) and his wife (married 22 I 1924), Meriel Christian Maud BOWER (25 XII 1900 - 27 II 1973), of that LG family, formerly of Welham, North Yorkshire.
