from Sol Norton

FLORENCE NORTON, ┬áborn 1871 Auckland, died 1923 England (Probably Buckinghamshire) widow of lord Edwin Abercromby Dashwood, 8th Baronet of West Wycombe, Buckinghamshire, married Colonel WILLIAM SELBY-LOWNDES, JP, born 1871 of Selby House, Bletchley, B’hamshire in 1894.
After his death she married, in 1910, ALFRED RONALD GILBEY, son of Alfred Gilbey of Wooburn House, B’hamshire.
Sol’s question is, if anyone has any information on her daughter of her first marriage, Florence Emily Dashwood born 1890?
In my papers drawn up by a relative in NZ there is a Diana Selby-Lowndes, born 1909. Is she a daughter or daughter-in-law?
Thank you in advance.
Cheers,
Sol Norton
