According to the 1851 census for Hertford, William was born in Littlebury, Essex about 1808. He died in Hertford in August 1854 aged 47.
Daniel Odell(of Thundridge, Herts) and Rebecca Plaier (of Essex) married in Littlebury in1803 so may have been his parents. They both died before 1820 in Hertford.
Any help appreciated.
