Hello there Ivan, i've got a little further back than you in the area of Somerset/Dorset.
Henry B:1739 (Penselwood)
He married a woman named Jane Cox in 1762 in Shaftesbury.
His parents were: Henry and Mary Married in 1740
Henry B:1704 Stoke Trister
D:1760 Silton
His parents were William and Elizabeth married in/before 1704
William B:1680
D:1756 Stoke Trister
Before this is hard to see, because the church in Stoke Trister was knocked down in 1841 and replaced later on.
