Francis Parsons' career is quite complex as he worked with a number of business partners. The dates are approximate but as accurate as we know of:

13th December 1797 - Alone
22nd December 1797 to 25th March 1800 - with Stephen Crees
28th March 1800 to 28th November 1802 - Alone
4th December 1802 to 23rd March 1803 - with John Bennett (only 8 pairs of tongs were assayed (on 4th December 1802))
15th January 1803 to 31st May 1805 - Alone
8th June 1805 to 24th December 1806 - with Joseph Goss
2nd January 1807 to 6th August 1808 - with B Goss
19th August 1808 to 30th November 1810 - Alone
4th December 1810 to 6th August 1814 - with Joseph Goss
27th August 1814 to 2nd November 1815 - Alone
25th November 1829 to 20th August 1831 - Alone

Very often his partnerships are recorded as "Parsons & Co." so we can not actually be sure of any of these start and end dates.

Francis Parsons sent the following tongs for assay:

13th December 1797 - 8
28th March 1800 to 31st May 1805 - 590
16th August 1806 to 27th September 1811 - 555
