In another, currently unanswered, question (Where was Matthew Nettell, of Illogan, Cornwall, for the 1861 Census?) I sought the 1861 Census location for my 2nd great grandfather Matthew Nettell who was born in 1846 at Illogan, Cornwall and was recorded as being a Blacksmith on his 1865 Marriage Certificate (at Redruth, Cornwall).
Does anyone know the likely apprenticeship path he would have taken to assume this profession, and what records may be available for me to try and find where and when he may have done that?
