Thanks for your reply, Jorose
In the 1851 census, just months before his death, Henry reported his birthplace as Charlwood Surrey, though his name does not appear in the baptismal register.
I get the feeling that this family moved around a lot - especially if we are right and the brothers were merchants of one kind or another. Can you give me the date of the Times story so that I can order a copy and follow up on your lead? The Richard Page you have found certainly seems a more likely candidate than any I have so far looked at in the census of 1841 and 1851.
A person I have been researching, James Page (b 1825) who was probably the son of Henry, though Henry might have been his uncle, was a multilinguist and had worked in commerce in Hamburg before migrating to Australia in 1850. In Australia he was for a time the French and Swiss consul (or vice consul) and had a business as a shipping agent.
Valda -
many thanks for your reply too. I found a notice of Charles Page's death in the 1855 Gentleman's Magazine 'of Oxford Terrace, formerly of Oporto'
