Mr Gibson replied with a quote from a reference source, that said that there were holdings from some overseas places put no BT's were held in the Bishop of London's records for Jamaica and in fact he knew of no other likely source. Recently on the internet, I have seen suggested that Lambeth Palace may be a potential source for BT's from the West Indies, not specifically Jamaica, but I have not yet explored this resource. Essentially all records preserved in Spanish Town after 1824 are Bishop's Transcripts, because they were transcribed by the Rector of the parish, and sometimes previously the curate, who sent them in to the Diocesan Office where the clerks transcribed them into books. This is something to keep in mind, because if three different people transcribed them, that always opens up room for errors to creep in. A Visit to Salt Lake City to the Family History Library is a possibility.
Visitors come from all over the world and North America, and summer is particularly busy.
Some commercial firms and some genealogy organizations do arrange for 3 - 7 day trips for this purpose, arranging accommodation and air travel. You should be aware that because of crowding on the Latin American floor, at the present time, Jamaican films are no longer housed in the open cabinets on the floor. Instead you need to request the films giving the numbers to the staff, who will get 5 films at a time from the high density storage which is not open to the public. Some of the most recently released films in the catalog may not even be in Salt Lake City but still at the vault. Otherwise your short trip may turn out to be a disappointment.
