The National Archive of Memorial Inscriptions (NAOMI) is a U.K. website which might prove to be a valuable source of information for family historians. It comprises a searchable database of memorial inscriptions from English counties that the company has been developing since 2005. The site now lists over 182,000 names from 630 burial grounds in Bedfordshire and Norfolk, and more records from other locations are being added on a regular basis.
Memorial inscriptions can be difficult to find for family historians in the United Kingdom, and the task is that much more difficult for genealogists outside the country. This site enables anybody to search the database and obtain important information free of charge. If you find a relevant entry, then you can purchase the inscription for £4 with possible extra information, in the form of a photograph and a plan of the churchyard and some historical text about the church, for an extra £1 for each of these, if required.
