Your message was posted a few years ago!!! So, I don't know whether you will still be watching out. I am also researching the Jebbett family. I am back to the 1500's but with a problem at the top which is currently being researched further. My main task now is to link the Jebbett's of Shackerstone/Newton Burgoland with the Jebbett's of Warwickshire - Higham on the Hill and Chilvers Coton. So far I have had no luck.
However, you mentioned Eastbourne. As I see it William 1851 born in Rolleston, son of William 1812 born Shackerstone. Married Louisa Tolley they had Annie, George1886-1956 (died Eastbourne) , William 1888, Ernest, Lilian May. William 1888 married Amy Durham, they had William George E 1909, Annie, Ernest, Esse B, Rose, George, Charles, Jean E. William 1909 married Louisa Cuddington and they had Margaret 1946, William A 1938 - he married MAria Irving and they had Nicola and Kersten. Charles married Jean and they had Jane and Jennifer. So, the males are few and far between.
If you want to write to me I will give you my email address.
