Various documents show Michael Horton BUSBY to have been born 1803, at Chesham, Buckinghamshire, but, I have been unable to find any record of his birth/baptism/christening.
You could always reach out to the Bucks FHS, as they might have better Chesham baptism coverage for the period you are interested in.

If they had a free online index search facility, so that, if and when, a search finds the presence of a record, the user can then pay to obtain a copy of the record, that would be more appropriate than to simply pay them to do what I have already done - I had spent many hours, searching through microfiches, searching for the record that I could not find.
The web page, to which, the above, links, shows no evidence of the record.
If I could find the record, in a free online search, I would rapidly pay to obtain a copy of it. But, the above linked web page does not show any evidence that they have access to the record, that I have been trying decades to find.
