The Samuel Davey who died in Bideford died Dec.qtr.1883 (not 1888) and shown as bc.1795.
1851 Census at West Putford shows this Samuel Davey as bc.1793 West Putford, with 2 daughters and a 10 month old grandson - Samuel Hutchings Davey (b.1850).
Samuel senior married as Samuel Davy to Ann Broom 24/3/1823 West Putford.
Ann bc.1794, buried 7/1/1844 West Putford
Samuel bc.1795, buried 26/10/1883 West Putford
Samuel Davie bp.14/6/1795 West Putford, son of Samuel and Grace
Samuel junior appears to be the son of Mary Davey who married a William Hutchings Mar.qtr.1852 Torrington. A son John born Mar.qtr.1853 Torrington, and a James born Mar.1855 Torrington - these 2 boys are with their parents in 1861 but aside from the 1851 census entry I can find no further trace of their elder son Samual Hutchings Davey under either Davey or Hutchings.
