What's in a name: Firms' simplified family trees

Between January and December 1989, accounting historian Peter Boys prepared a series of simplified family trees showing the development of the big accountancy firms of the day.

The original trees from 1989 have been reproduced here with a series of textual updates from Peter Boys which have taken the story forward to May 2005, the 125th anniversary of ICAEW. Since then, the staff of the ICAEW Library & Information Service have added notes on further changes that have taken place.

If you are aware of any further information which would add to or improve the accuracy of the family trees please let us know. You can contact us at library@icaew.com
