The Moores acquired tenure of Demesne Land at Rushen Abbey very soon after the Dissolution. The Abbey Computus of ?1540/41 has a "Johanne A. Moore" (whatever that represents) paying (Demesne Rent?) of 33s 4d. The surviving Lib. Assed. of 1540 has the relevant rent paid apparently by others, although John More paid substantial rents in Castletown.
