John was about ten in 1800, so it seems likely that the original "free" tenant was his father, although he might have taken over the tenancy of someone else. John worked for Ordnance Survey, perhaps his father did too? Obviously there is more work to be done.

Sitting right next to the tombstone of Williams g.grandparents, Michael and Ellen (Linehan) Donovan is a Shanahan Crypt. Perhaps this is the family of his g.g grandmother Mary Shanahan, the wife of John Donovan.
