Trace the history of an accountancy practice

Research guide

Published: 24 Sep 2014 Updated: 19 Oct 2022 Update History

This guide is intended to provide a guide to the resources available from the ICAEW Library & Information Service that can be used to trace the history of a firm.


This checklist provides a quick run through of the steps that you can take to research a firm using the resources of the library. You can complete many of the steps yourself, using our online resources.

For the research steps requiring access to printed volumes in our collection, you are welcome to come in to conduct your own research though we would recommend that you notify us in advance so that we can make sure that any materials you require will be available for your visit. If you are not a member you can pay to access the library for a day or for a week in order to conduct your research – see who can use the library for further details of our current charges.

Alternatively, the enquiry team can conduct research on your behalf. See our section on research charges for further information.

Basic research steps

Sources part 1: The accountancy practice

The approximate date of establishment for a firm can often be revealed by tracing the individual history of the founding partners. You may find that the membership lists record the first year that a firm’s name appeared, allowing you to focus research on a narrower time period.

Similarly, the membership lists can be used to trace the different addresses used by a firm and the opening of offices in new locations. The lists can also be used to try and find out what happened to a firm if it has disappeared from view.

Tracing firm names and addresse

The library holds a set of the annual volumes of the ICAEW List of Members, from 1881 to date. The volumes include an alphabetical list of firms, showing the partners’ names and the address of the firm. There would also be an alphabetical listing by town which later became the official ICAEW Directory of Firms.

The alphabetical list of firms is a good place to start to trace different addresses used by a firm and the opening of new offices.

It is worth remembering that individuals may have been involved in more than one firm – or that the branch of a firm opened in another country may have had a subtly different name (e.g. an additional partner may have been listed in the firm name).

This would require research using the annual volumes which can be a time consuming process. You can either pay to use the library for a day or you can pay for a member of the enquiry team to conduct research on your behalf.

Tracing firm names and addresses

You may be able to find notices about the opening of a new branch or a firm taking on a new partner by following up changes noted in the membership lists within periodicals such as ‘The Accountant’.

This would require research using the accounting periodicals in our collection. You can either pay to use the library for a day or you can pay for a member of the enquiry team to conduct research on your behalf.

Founder firms

The expression 'founder firm' is not a recognised term but one which was introduced by Harold Howitt in his ICAEW history (published in 1966). In his book Howitt used this term to describe firms which could claim continuous partnership descent from a signatory to the charter or a member of the first council. The list published in the book also included firms which could claim to have been in existence for at least 100 years. You can consult Howitt's book in the library to see if the firm is included in this list (notes of varying length are provided for each qualifying firm).

A later book, Chartered accountants in England and Wales (ed. Wendy Habgood), published in 1994, also included a listing of the founder firms in an appendix. Appendix III: Founder Firms listed 32 firms that were descended from the first council members and a further 43 firms that were over 100 years old in 1965 and not included in the first list, as well as providing a correction to the list produced by Howitt.

Tracing mergers

Family trees

What's in a name: Firms' simplified family trees shows how firms have merged over time to form the largest firms of the twentieth century. You can use the A-Z of firm names to identify any firms included in the family trees.

Membership lists

The membership lists can help us to understand what happened to accountancy practices which have subsequently disappeared from view.

The last entry for a firm in the membership lists should show the names of the partners and address details before it disappeared. We can sometimes follow through what happened to the firm by looking at the addresses of individual partners. For example, you may find that all the partners were listed in the next volume at a different firm – which might indicate that a merger or acquisition has taken place.

Accountancy press

The accountancy press may have included notices about changes to a firm, such as a change of name or a merger. Once you have narrowed down the date of a change using the membership lists you can sometimes find a corresponding notice in the accountancy press around the same time.

Sources part 2: Individuals in the practice

There are a number of sources that can be used to provide further detail about the partners, articled clerks and other individuals associated with a firm.

Obituaries and biographical profiles

The Accountancy Ancestors database is an index that records obituaries and biographical profiles of accountants from 1874 to 1965. You can use this to track down obituaries for the founder of a firm and other individuals associated with the firm.

The list is available in a version arranged by the name of the firm, identifying those individuals associated with a firm. This might be the firm they were first articled to, a firm they spent some time working at, or the firm at which they ended their career.

The length of an obituary can vary considerably – from a few lines to a few pages. These are more common in the period between 1880 and the middle of the twentieth century, after which the increase in the membership numbers made writing them impractical.

Free to view the index.

Obituaries/profiles can be supplied for a charge.


The Accountancy Ancestors database includes an index of photographs – this might be a photograph of a single individual, a group or a cartoon. You can use this to try and track down any images of the founder of a firm or other individuals associated with the firm.

Free to view the index.

Copies can be supplied for a charge.

First World War

With the colours

The articled clerks and accountants in the firm may be listed in 'With the colours; a list of Chartered and Incorporated Accountants and their Clerks who are serving with the British Forces on land and sea, 1914-1916'. The publication includes an index by the name of the accountancy practice.

First World War Index

The individuals in a firm may be included in the First World War index which covers entries from the accountancy press. This includes reports on accountants, their staff and close relatives who were wounded, killed in action, mentioned in despatches, awarded medals or taken prisoner.

The publication includes an index by the name of the accountancy practice which allows you to view the details all individuals associated with the firm who appear in the index.

Free to search.

Entries can be supplied for a charge.

Other sources

The sources listed above can be augmented by other data sources that can be found in print publications such as pass lists of candidates and the names of the winners of examination prizes.

Where else can I find records relating to the firm?

A survey of the historical archives held by accountancy firms’ was published in 1994, with a brief paragraph about the history of the firms. The book ‘Chartered accountants in England and Wales- a guide to historical records’ by Wendy Habgood (Manchester University Press, 1994) can be consulted in the Library.

The National Register of Archives provides information about the location of historical records, including those of accountancy practices. The corporate name index allows you to search for a business or organisation.

The records of some accountancy firms have been deposited at local archives. The Access to Archives search engine allows you to search for documents in the care of local record offices and libraries, universities, museums and national and specialist institutions across England and Wales. However, in some instances you may still need to contact the appropriate local archive to find out what they hold in their collections.
