Although only tenuously contected to the Raishbrooks I know have an extensive family tree for them. They appear to have originated from the the marriage of Eliza Pryke to George Raishbrook - the surname probably being changed from Rushbrook at the time of their marriage or thereabouts. Anyone with the surname Raishbrook will be linked back to this couple who married in 1830. Anyone wanting info can contact me direct on heatherscards@hotmail.com.

Hi Heather
Only the first six known children to George and Eliza were actually George's children (namely, Eliza, George William, Eliza (2nd), Robert, William, William(2nd). Those from Henry Carder Raishbrook onwards through to Arthur Carder Raishbrook were all the illegitimate children of Eliza and John Henry Carder who eventually married in 1863. While the baptisms and birth certificates state their father was George, it is now generally accepted because of the middle name given to albut one, that their father was actually John Henry Carder. I suspect that George Raishbrook probably died around 1863 hence the late marriage to avoid a bigamous one. However no death has yet been found.
To anyone interested in George and Eliza's children (unfortunately not the later ones as their father was John Henry Carder) I do have an ancestral line for George in Essex. Please email the address on the homepage detailing which of his children and grandchildren you are descended from.
