I found this on Dr. Herbert D. Percival on Newspapers.com recently:
H. D. Percival, M. D. of Covington, Kentucky, is in the city and has paid a visit to the chamber (Los Angeles Chamber of Commerce.) He is sent here by a heavy corporation at Covington engaged in the Manufacture of glass. If He can find land suitable to his purpose and a supply of natural gas, a factory will be set up which will employ seven hundred hands. [Los Angeles Herald, Wed. Aug 20, 1890, p6.]
Well, that explains why he went to California. And I think I know the company in Covington. That would be Hemingray Glass, who made glass insulators.
I learned something new!
