This card index was compiled and donated by the professional genealogist Brian Brooks in 2002. Its coverage is not comprehensive and some counties receive fuller treatment than others. Mr Brookes still holds the cards for London, Middlesex, Sussex and Wales and these are not included in the computerised version.

The index was compiled from numerous sources including the following:

The Law Lists for 1780, 1790, 1793, 1800, 1802, 1805, 1808-1828, 1830-1840, 1843-1849, 1851-1855, 1861. The 1861 edition has sometimes been used to show date of admission.

1851 census

The Clerks of the Counties 1360-1960 by Sir Edgar Stephens, 1961

This digital version of the index is divided into two parts: one giving details of the solicitors career and one giving genealogical information.
