Hello, I believe that William Cossam was my 4 X Gt Grandfather. This is my line: William Cossam 1718 - 1745 married Elizabeth Nutley next generation: Dinah Cossam married William Thompsett next generation: Lydia Thompsett 1801 - 1861 married Thomas Hopper 1798 - 1875 next generation: George Hopper (property owner in Lewes) 1826 - 1890 married Lucy Finch next generation: Henry Hopper 1863 - 1898 married in 1896 Emily Rainbird. Prior to that, Henry, (a baker in Lewes) had a son Cecil Harry Hopper Wiseman (born 1892) by Lilian Kate Wiseman. Lilian, at some point went to live in Acton. On 5 April 1898 Henry threw himself under a passing train at Acton Station. On his death certificate his occupation is given at this time, as Bookmaker, of 63 Cavendish Place, Eastbourne. He and wife Emily had a young son William Henry Hopper born 1897. Emily remarried (a Herbert Smith). William was raised by Henry's sister Clara Ann Lydia and her husband Arthur Harris. Arthur was Bank Manager and lived at Bank House, Barclays Ltd, Terminus Road, Eastbourne. William became a pilot in the RAF and was living in Cairo, Egypt in about 1919. There, my trail goes cold. I have tried to find further information on the Rainbird and Harris family but been unsuccessful, so far. I should dearly love to find out more about William Henry, who would have been Grandad's half brother. Kind regards Jill
