The Society of Genealogists have an increasing number of online datasets available to their members. The Whitehead Collection mainly focuses on East Anglia, but does have entries from other counties.

Whitehead collection of monumental inscriptions

These monumental inscriptions were recorded by the professional genealogist L Haydon Whitehead and donated to the Society in 1985 after his death. They are part of a much larger collection of material compiled by Whitehead which included transcripts of wills, Hearth Tax returns, parish registers, Bishop’s Transcripts etc.

The collection focuses on East Anglia, and the greatest number of MI recordings are for Essex (31,000) and Cambridgeshire (12,000). However there are entries for many other English counties (Derbyshire, for example, has more than 6,000). Some of the stones recorded by Whitehead are no longer legible, making the collection particularly important.

At present the Members’ Area includes only an index to the Whitehead MIs, which has been subdivided by county. The full inscriptions can be consulted on cards in the Upper Library, or photocopies ordered through the Society’s Search and Copy’ Service . However the cards have recently been scanned and it is hoped to include images of them on the Members’ Area in due course.
