I wrote to the The Weald genealogy and the real birth date of Edward Jenner was 13 March 1803 and not 1806, he died on his birthday 13 March 1872
I received the following information from The Weald:
I believe that the Edward Jenner story is as follows:
He married Nancy May on 6th Aug 1827 at St John-the-Baptist, Southover, Lewes
They moved to Brighton where their first child Ann Elisabeth was baptised on 17th Jan 1830 – Edward’s occupation is ‘Stationer’
Their second, third, fourth, fifth and sixth child are baptised in Brighton where his occupation is ‘Hairdresser’.
In 1841 the family moves to Lewes where they are recorded on the 1841 Census. Edward’s occupation is listed as ‘M.S.’ or male servant.
They have two more children in Lewes where Edward’s occupation is ‘commercial traveller’
In 1851 the family (less the two eldest daughters who have moved away) is recorded on the census where Edward’s occupation is ‘Commercial traveller for a publisher’
In 1861 the census shows Edward and Nancy plus two of their sons. Edward is a ‘Commercial traveller for a printer’
In 1871 the census shows Edward now widowed living with his son Philip and his family. Edward is a ‘Commercial Traveller to Sussex Express’
Edward died in 1872 and is buried at St John-sub-Castro, Lewes at the age of 69 on 10th March 1872.
There is only one family in Sussex with parents Edward and Nancy Jenner
I hope this helps
Edward Jenner married Nancy May 6th August 1827 at Lewes St John Southover. I cannot find his parents but she was born 16 Sept 1802 at Brighton and baptised on 2 Jan 1803 at St Nicholas, Brighton. Her parents were Samuel and Ann May.
I hope this helps
You may also be interested in the following transcription of the Jenner gravestone at St John-sub-Castro:
In/ Loving Memory/ of/ Ann, Widow of the late/ Philip Walter Jenner/ who
died June 15th 1902/ aged 60 years/
Sacred/ to the memory of/ Nancy wife of/ Edward Jenner/ who died February
26th 1869/ in the 67th year of her age/ also of/ the above named/ Edward

Philip Walter Jenner/ son of the above/ who died June 13th 1882/ aged 39
Footstone: AJ 1902; NJ 1869; EJ 1872; PWJ 1882.
Fascinatingly the burial register has Edward buried on 10th March 1872 which I have to presume is a transcription error for perhaps the 16th march.
I also found an entry on ODNB:
Jenner, Edward (1803–1872), botanist, who was born on 13 March 1803 in Heighton, Sussex, was for forty-seven years traveller to the printing house of Baxter of Lewes, publishers of the Sussex Express. Although quite ignorant of Latin, he worked hard at entomology and botany, securing a close and critical knowledge of the freshwater algae. He was elected an associate of the Linnean Society in 1838. The cryptogamic portion of his admirable little Flora of Tunbridge Wells (1845) gives it a distinctive character. He provided the illustrations for John Ralfs's The British Desmidieae (1848). He married, at St John the Baptist Church, Lewes, Sussex, in 1827, Nancy May (1802–1869); they had at least six children, five sons and a daughter. He died suddenly at Lewes, on 13 March 1872, his sixty-ninth birthday.
Even though I have not been able to give you the names of his parents I hope this information will be of intrest to you
