I looked through everything I could find and found no 'Frisco' Hotel in Sherman. I have an old bud that lives near there so I will hit him up. I will ask about the other also.
I found an old El Paso newspaper article about 3 men, one of which was C. L. Gilbert, 'prominent citizen' of Plainview, that was critically injured in a car crash in Plainview on Nov 9, 1910. Can't be two C. L. Gilbert's!!! "Cause of accident, travelling too fast"!
Thanks, that is more than I had! I love the telephone number 219. As far the hotel, someone said they found something about their liquor license being approved around 1910, so it would be about 100 years ago. Let me know if your friend knows anything. Thanks!
