Jane MacNamara was kind enough to point out to me a posting on the York yahoo group, via http://www.yorkfamilyhistory.org.uk/, about local BMD indexes.
There are two sets of Birth, Marriage and Death indexes in the UK; the original indexes held by the local register offices and a secondary index created by the General Register Office.
Many of the local indexes are being transcribed by the local authorities in conjunction with Family History Societies, and the data placed on-line. Check availability via http://www.ukbmd.org.uk/
The local index, where available, is less liable to clerical errors. You may also be able to determine the church in which a marriage occurred from the local index entry.Mentioning Jane also reminds me to draw attention to the Toronto Genealogy Summer Camp, for adults, August 12 - 17.
