The early history of Armitage & Norton is: Charles Payne c 1868; Chadwick & Armitage pre-1879; Armitage, Clough & Co 1880 (Chartered Accountants in England and Wales: A Guide to Historical Records, Wendy Habgood (ed), Manchester University Press, 1994).
Thomas, Wade & Guthrie started in practice together in 1875 either under that name or as Thomas, Wade, Guthrie & Co; the latter name had certainly been adopted by 1877 (The Accountants' Directory 1877, Alfred C Harper (ed), Williams & Strahan, 1877).
Update
Peat Marwick McLintock became KPMG Peat Marwick McLintock in early 1990 to reflect its international network of firms.
KPMG Peat Marwick McLintock became KPMG Peat Marwick from 1 October 1991 (Accountancy, July 1991, p.17).
KPMG Peat Marwick became KPMG in February 1995 (Accountancy, March 1995, p.25).
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
