Here is the link to today's column:

As I mention in the column, I really can't find a single explanation for
Clyde's 19th century rise as a given name that's satisfactory to me. The entry for
Clyde on this site mentions the creation of the title Baron
Clyde for the British general
Colin Campbell in 1858. The timing is right, but considering that most of the Clydes born in the 1860s and 1870s had working class parents in the Midwest, it is hard for me to believe that this could be the only factor. Baron
Clyde retired a couple of years after he was given that title, died in 1863, and the title died with him since he had no children. Why would so many farmers and mechanics in Ohio and Michigan have named sons after him?
There are two other explanations in the column, about the poem "
Clyde" and the
Clyde Line steamship company, but neither of them by itself seems adequate to explain the pattern of use. I should mention there was a local Revolutionary War hero in the Mohawk Valley area of New
York State named
Samuel Clyde. That might fit geographically as Michigan, Ohio, and Iowa had a great many early settlers from upstate New
York. But why wouldn't
Clyde have boomed a bit earlier than the late 1850s if a Revolutionary War hero was responsible?
So at this point I think the big increase in Clydes is still a bit mysterious and we can just say the name was "in the air" and fit in with the fashions of the time.
