William Henry Hooker b. 1873 does not appear in the 1841 census as by that time he had moved to Canada, but he is a person of great interest as he may have been the brother of the elusive ancestor Robert.

Evidence for that is as follows –
Robert was married in 1812 at Christ Church Newgate (to Elizabeth Cleaver) and a witness to the ceremony was a W.H.Hooker.
William Henry’s first marriage (to Elizabeth Tippens) was at Christ Church in 1814 and a witness to the ceremony was a Robert Hooker.
Robert’s first son was called William Henry.
William’s first son was named Robert.
Robert’s occupation was sometimes mathematical instrument maker and sometimes hairdresser.
William’s occupation (before he left for Canada) was hairdresser.

On Ancestry.com there are some family trees which feature William Henry Hooker after he moved to Canada – the amount of detail is amazing and even includes the names of his parents ie Thomas & Elizabeth! However, even with that knowledge, I cannot find Robert’s birth!
I have written to the owner of one of the sites, to see if he has any further information on William Henry’s family in England – fingers crossed!!
