all deeds (transfers of property) are public - however for this period you will need to search at the Land Registry (Douglas) - the indices to older deeds are in the Manx museum arranged by parish + date - you need to seach down these looking for a known vendor or vendee (the index gives no information as to property). The Land registry is currently being computerised and tied into the new digital mapping of the Island but I don't know when this becomes publically accessible.
