I will try to contact the Hillerys for verification. I have also found Henry Blades listed in a book " British Army Pensioners Abroad : 1772 - 1899" by Norman Crowder. I ordered the book this week and will let you know what further information it can provide. I am hoping for a detailed summary of his service and pension. I will keep you posted. If this is our Henry Blades then he belongs to "The Chelsea Pensioners". A group of British pensioners so named because their pensions were administered by The Royal Hospital in Chelsea, England. Once I have his Regimental info I should be able to trace him through these records. It will show his full name, date of admission to the hospital, his age, rank(s), time of service, and the rate of pay.
I have found Francis Blaides listed in Church Parish records from Richmond, York. The time line is right and some of the siblings are also listed. I'm sure there are more records there that are not internet accessible since Richmond is a very old town going back to before the Norman Invasion in fact Richmond is an angloized French place name.
