Hello Andrew,
Rather an old thread I know but I’ve only just seen it whilst researching my wife’s family tree.
From what I have found my wife’s (Catherine BLUNDEN) great-grandparents (and your great-great-grandparents) were John (b 1838 Chithurst) and Emma (b 1841/2 Westbourne) BLUNDEN. In the 1911 Census they were living at Upperton Tillington and had been married for 47 years, putting the date of marriage in 1864/5. A John BLUNDEN married Emma WEST in Chithurst on 8th July 1865.
They had eleven children, including Leonard Lewis BLUNDEN (b 1882 Lavant) and Reginald Douglas BLUNDEN (b 1884 Hunston). Others were Edith, Ernest, 2 × Georginas, Walter, Percival, Beatrice, Elizabeth and Lawrence.
Leonard married Martha Georgina REDIT in 1909 in the St Giles District of London. A daughter was born in Cooksbridge in 1911, Dorothy Georgina Esther BLUNDEN. In the 1911 Census the family are living at Railway Cottages, Cooksbridge and Leonard is employed as a signalman for the London, Brighton and South Coast Railway. In 1921 he was killed by a train on Itford Level Crossing, between Beddingham and Newhaven.
Reginald is my wife’s grandfather, he died in 1934. My wife’s father, Leonard Lewis BLUNDEN (b 1924 Beddingham) remembers an Aunt Martha who lived in Newhaven, presumably your great-grandmother.
Hope this helps,
Richard.
