The agricultural census of 1803 is less helpful in placing a given adult male in a given townland and using that to distinguish which is which. It appears that some of these men had multiple holdings and not infrequently in adjacent townlands possibly as inheritance via female line married-in and then given a bequeath. I built a spread sheet and stacked columns by townland using the other three documents as rows, and then just stacked up the male names under each townland. Then of course, there were different townland names in those census documents that have to be researched. There will always be some heavy lifting, often for minimal return, except maybe to exclude rather than confirm.
