Hi Jane,
Please could you try to look up John Taylor, b.1835 North Shields, Tynemouth, England. In 1851 he was a Chemist's Apprentice and in later census gave his occupation as a druggist.
In 1891 he is living at 41 Linshill Terrace, North Shields, he was a wholesale druggest drysalter.
In 1901 he is living at 25 Spring Terrace, Preston, Northumberland, he was 65 and a retired Chemist.
He lived and worked in North Shields all his life.
I appreciate Taylor is a common name but hope you might be able to find something.
Thanks
Laurina
