Black Hawk and Blackhawks
Add comment March 10th, 2009
The famed Native American leader for whom many things around these parts are named was Chief Black Hawk. When referring to him or the war in 1832 or the statue of him in Ogle County, it’s “Black Hawk,” two words.
For the names of area businesses, organizations and roadways, it’s predominantly “Blackhawk,” one word.
And one word for the National Hockey League team from Chicago.
So, historical uses, two words; current ones, probably one word.
Also notice above, it’s “predominantly,” not “predominately” — “ant,” not “ate.”
