|Ford Model T|
I was reading about the origins of Motor City and came across quite a few possibilities. There's Henry Ford, of course. "Henry" peaked in the 1800s and is currently staging a comeback. (There's also Henry Leland, who founded Cadillac and Lincoln. Leland can work as a first name as well.)
Is it because parents are nervous about naming their child something closely associated with kidnapping? Keep in mind that the word can also mean "redemption," folks.
Ransom = Bad. Ass.
Hugh Chalmers founded Chalmers Motor Car Co., which ultimately became part of Chrylser.
Joseph Hudson and Roy Chapin, meanwhile, started the Hudson Motor Car Co. — a precursor to American Motors. Between them, there are four potential names there. (But Chapin's middle name was Dikeman, which I wouldn't advise for a boy or girl.)
Charles Nash was a president of GM, who went on to found Nash Motors. Again, both first and last names are solid, though "Nash Bridges" may have tainted that name. Horace Elgin and John Francis Dodge were then men behind the Dodge Brothers Co. "Elgin" had a brief spike in the 1910s as a first name, before fading back into obscurity.
David Dunbar Buick incorporated the Buick Motor Co. in 1903, and later allied himself with future GM founder William Durant. Walter Chrysler started that company in 1925 when the Maxwell Motor Co. was reorganized. (Jonathan Dixon Maxwell founded the precursor firm.)
Finally, Alanson Partridge Brush founded the Brush Motor Car Co. and later formed the United States Motor Co. with brothers Benjamin and Frank Briscoe.
Here's a list of the names, along with when they peaked in popularity.
Chapin (never ranked in the top 1,000)
Hudson (peaking now)
Nash (peaking now)
Dixon (never ranked)
Maxwell (peaking now)
Alanson (never ranked; Alan peaked in the '50s)
Benjamin (peaking now)
