Evening Toni*,
I confirm that Edward Culmer, a carpenter, was baptised at St Mary the Virgin in Dover on 19 September 1810, the youngest son of William Culmer and his wife Mary nee Hayward. Another son of William and Mary was indeed George Culmer, fisherman and later a fishmonger, who was baptised at the same church in 1791 (actual date not yet found). This George married Elizabeth Brice at the same church on 9 July 1809 and their eldest son, William Henry Culmer was baptised in Dover on 22 August 1810. I don't have a marriage for him and have him being probably dead before Q3 1837 as I haven't found him so far in GRO bmd records.
Going back to Edward, he married Annie Cole in 1830 and they had children as per 1841 census in Limehouse: Mary in c1829/30, who I believe went into service; George Isaac born 24 August 1831, who eloped to Brooklyn NY with his girl friend in 1853 leaving his pregnant wife Sarah behind in London. (Sarah married William Whitehead in Q3 1856 and their 2nd son was the infamous Frederick William Whitehead); Annie Susan, bpt 1833, who married Noble Edwin Smith in 1859 and finally Alfred born c 1835. No baptism records for Mary or Alfred, but both believed to have been born in Dover.
Edward died in the Tap Room of the Bull & Mouth Inn on Bull & Mouth Street in the City of London on 6 March 1849 of "Typhus, 14 days, certified" according to his death certificate, but quite how he managed to drag himself from the family hovel in nearby Bartholomew Close to the "Tap" for his last pint is quite remarkable.
