I've been chewing over the non appearance of names in the Tithe Lists and the Griffiths. Would I be correct in thinking that a name would ONLY be recorded if that person held a lease on the land that he / rarely she lived and worked on? In other words, the head of the household / family's name would appear, but the sons who were working and living in the same place, would not appear. I am minded of the instructions given to the census data compilers about farmers and their children who would appear as ' farmer's sons and daughter ' - but only if living in the same house. If they were living next door, say married with their own family, yet working on the family farm, they would not be termed ' farmer's sons ' but agricultural labourers. Might a similar situation account for names not appearing in the Tithes and Griffiths - even when we know for certain that they were living in a particular town land and parish? A puzzled Mary
