Crisp's Visitations of England, Wales and Ireland were originally published between 1893 and 1921, and a complete set, plus notes, is held in the Society's Upper Library. The works record the pedigrees of the "last three generations" of families who had been granted Coats of Arms shortly before the publication of the volumes.

This index to the pedigrees, compiled by Dr Andrew Gray, enables the researcher to check whether a pedigree for a particular surname appears, and in which volume.
