My gt gt grandfather, Harvey Piper, was baptized as an adult at St. Sepulchre in April 1829. His brother, Henry, was also baptized as an adult about a month later at the same church. I have been searching Nonconformist sources to try to trace their actual births (the adult baptism records do not state their ages) but have gotten nowhere. Can you suggest any other sources to try? According to the censuses, Harvey was born in Chelmsford. I didn't find Henry in any census.
