Quite a few of my GUEST relatives were pharmacists and druggists according to the censuses and various certificates.
A distant relative who contacted me via ancestry's web site, had asked the Royal Pharmaceutical Society about one of them, and they had replied to say that he's in the Register of Pharmaceutical Chemists and Chemists & Druggists and for £20 they will be able to dig out the following info:
• Date of registration with the Pharmaceutical Society of Great Britain.
• Type of examination taken, examination number and qualification obtained.
• All registered addresses and the dates they changed.
• Date of removal from the Register and sometimes the reason why (e.g. death).
Seems fairly good value, though neither of us have yet got round to sending off a cheque. There are a few more I'd like to check too, so this could get a bit expensive!
The one I know is on the Register is Frederick William Guest (b. 1809, a chemist in Tonbridge, then Hawkhurst, then Folkestone, before retiring to London by the time of the 1871 census), but some of his brothers were also in the profession, and most of his sisters married pharmacists:
John Henry Guest (1818-1891, who was a Chemist & Druggist on London's Ratcliffe Highway on the 1841 census (but by 1846 was working on the railway, so I'm not sure whether he would have been registered).
Edward Guest (1821 -), described as a Chemist on his marriage certificate to Margaret Lemon at Clifton, Bristol 17 Feb 1858.
Jane Clarissa Guest (1824-1912) who married Frederick Biggs (1829-) a Chemist & Druggist in Swansea on the 1851, 1861, 1871 censuses, becoming a colliery agent on the 1881 and 1891, though on the 1901 he calls himself a retired chemist, and on his wife's death certificate, he's a Chemist & Druggist.
Charles Guest (1826-1863), a Chemist in Clifton, Bristol in 1849, 1850; a Chemist & Druggist on the 1851 census; a Homeopathic Chemist in the 1851 Mathews Bristol & Clifton Directory; Homeopathic Chemist in Clifton in the 1856 Post Office Directory; a Chemist in 1858, homeopathic chemist on the 1861 census and a Master Chemist on his death certificate. His shop/residence was at 31 The Triangle, Clifton, Bristol, most of that time.
Ellen Sophia Guest (1827-) married Edwin Wheeler (1831-) in January 1856 in Bristol. Edwin became a Homeopathic Chemist in Cheltenham (employing an apprentice and a boy on the 1861 census) until Charles Guest (above) died, when he seems to have taken over 31 The Triangle in Clifton. Though by the 1901 census he's moved to Queen's Rd, Bristol and is described as a Homeopathic Chemist, working at home.
It certainly looks as though there was a distinct marriage network in the pharmaceutical profession in the early to mid 19th century!
