There would appear to be a connection between James Sturrock (1821-1898) and my John Sturrock (abt 1780-?), who was also listed as a 'Perfumer and Hairdresser' in Cupar, Fife on the record of his marriage and on his children's baptismal records.
John Sturrock married Amelia Bonnar, the daughter of Alexander Bonnar, a brewar, in Dundee, Angus on 15 January 1810. They had at least three children in Cupar, Fife - Alexander (b. 1810), Emelia (b. 1812) and Charles (b. 1817).
I am a descendant of John and Amelia's daughter Emelia Bonnar Sturrock (b.1812), who married William Glass Stewart, a teacher, in Cupar, Fife on 24 November 1833 and who emigrated to Canada and had a large family.
Now that I've read this post, I will chase up what connection there is between William Sturrock and John Sturrock, since my John Sturrock and William's son James were both perfumers and hairdressers in Cupar, Fife! It would be interesting to hear back from anyone who might already have made the connection. My sources are from original documents downloaded from ScotlandsPeople.
