 From the Oxford Dictionary of National Biography: 
 The younger daughter of S. R. Platt, Nancy Quenelda Platt (1895–1993), proved to be the longest-lived member of the whole family. She never married but developed an avid interest in the history of the Radcliffe family. Her grandmother Alice had been a Radcliffe and two of her aunts had married Radcliffes. Her interest may have been influenced by the decision of her elder sister to prefer the style of Angela May to her given name of Alice, which was that of her grandmother. That interest culminated in the formal change of her own name, presumably by deed poll, from Platt to Radcliffe-Platt. She died at the age of ninety-seven on 28 April 1993 and was interred at Witherslack, Grange-over-Sands, Lancashire, where her favourite aunt, Emily Bertha Radcliffe (1858–1950), had resided until her death at the age of ninety-one, leaving £5345. The estate of Nancy Quenelda Radcliffe-Platt totalled £8,235,256: in real terms, when adjustment has been made for the depreciation in the value of the pound, it was much less than the estate left by John Platt in 1872.
