More thinking out loud, as I'm struggling with these Harradines, and I find it helps to put thoughts into writing.
We now think that James was born c1743, married in Old Warden in 1770, moved to Southill in 1785, died in Cardington in 1820 and was buried at Southill aged 77. Was he an unidentified/unbaptised son of John, whose marriage I can't find, who received a distribution of bread in Southill in 1753?
Then there's John who married by licence in Old Warden on 23 Oct 1776, not described as a widower so I assume he was a bachelor, moved to Southill in 1790, and whose burial after 1801 when he appeared in the census in Southill I can't positively identify. Did he move back to Old Warden where he was buried aged 86 in 1816? If so he's older than I thought. If it's not him, who was he? Not old enough to be the father of James though.*
The two of them seem to be of different social standing. James was an Overseer of the poor in Southill, and his children seem to have been relatively well to do, particularly the family of Samuel in Cardington. John's son Samuel moved back to Old Warden after marriage where he was an ag lab.
If anyone has any thoughts I'm in need of inspiration!

JP. This would inspire me:
