not all M/Cs survive - you can see this in some wills where a m/c granted many years prior is accepted as the will - often the m/c would be attested before a deemster then held onto by the parties concerned - if when property is transferred then post 1704 these must be recorded in the deeds (see north + south side sales), prior to this search Lib canc, lib scacc, lib mon (for abbey property) + even lib vas prior to 1704 - if property was not transferred at time of grant then no legal obligation to pass thru court post attestation - you can find occasional entries of lost m/cs with depositions of any surviving witnesses
