Small was my grandmother's maiden name and I have an avid interest in the family. I have a John Small born 7 Jan 1771, baptised 13 Jan 1771 in Kilrennie, Fife, Scotland. I don't have any children or any subsequent information, but his parents were Thomas Small and Elizabeth Brown married 18 Nov 1766 in Crail, Fife.
This is probably not relevant to anyone here, but I'll tell the story anyway as you're discussing Smalls.
You mention Kilrenny in Fife. Most people in that parish have always lived in the fishing village of Cellardyke, where I was brought up myself. In the 19th century the village was ravaged by regular outbreaks of cholera and other infectious diseases. Here is a story from a local news-sheet:
THE PITTENWEEM REGISTER, No.242, Saturday, September 29th., 1849
Remarkable Fact:- William Small, fisherman, who died of Cholera last week at Cellardyke, was at sea when the disease came upon him, and said to his companions - 'If there is such a thing as swallowing Cholera, I am afraid I have caught it'. When asked, what made him say so? he said, 'I felt as if something having the feeling of a soft cold potato had forced its way down my throat'. In less than five minutes after he made this curious remark he complained of pain in the stomach, - looseness of the bowels and cramp immediately ensued, and in half an hour after the first attack his countenance altered, and his features assumed the appearance of a dying man.
There are still Smalls in the area.
