If you are having problems locating an individual in the Irish Civil Registration Indexes, you may want to keep the following in mind: 1. Place names listed in the indexes are for districts. A city may be divided into several districts, while in the countryside, several villages may belong to one district. 2. Some events simply were not registered, even though it was required by law. 3. The years 1864-1870 have separate supplemental indexes for births and deaths. 4. Late registration of a birth or death will be found at the end of the index. (A separate section.) 5. There was no common spelling of surnames, so be prepared to search for different spellings. Also, surnames with prefixes (such as 'O' or 'Mc') may be indexed without the prefix. 6. These indexes were hand-written and do contain spelling and/or transcription errors, not to mention missed entries. 7. The events are indexed by the date they were registered, NOT by the date the event took place. So a birth that took place in December, may not have been registered until January. Be sure to search forward. 8. Some marriages are indexed only by the name of one spouse. 9. In the marriage index, a woman's surname may be the surname from a previous marriage, NOT her maiden name. 10. If the family provided the information, such as the age at death, it may be incorrect. 11. Many deaths were simply registered as 'unknown.' 12. If a child was born before the parents married, be sure to search under the mother's maiden name. 13. Some children were not named by the time their birth was registered, so they may be listed as either 'male' or 'female.' If you still can't find your ancestor in the indexes, then you may need to contact the church they belonged to. On another note, the LDS in Salt Lake City has the following on microfilm: 1. Marriage and death certificates for Ireland and Northern Ireland prior to 1871. 2. Birth certificates for Ireland and Northern Ireland from 1864 through March 1881 and from 1900 through 1913. 3. Birth certificates for the Republic of Ireland from 1930-1955. 4. Birth certificates for Northern Ireland from 1922-1959. Hope this helps! Take care, Tracy
