Hello, jlvolker, Jenny in Arizona,
I see you are looking for a William Williams, died 1877. You say you found him in the 1861 and 1871 census.... in the 1871 census, did he have an apprentice named William Pilkington Knight? If so, he is the same one I have posted an enquiry about, about 3 up the list from yours. The apprentice is one of my line, and I wondered what had happened to his employ. In the 1881 census my fellow was still a druggist assistant, but living with his wife, so I didn't know W.W, had died, if it is the same person.
