Thank you for your response and the information.
I believe the Charles Lemon Ervin you are writing about is the son of Chas Lemon Ervin (1842-1934). I had not heard about his mattress company but I know they were in the furniture business in El Paso. Thanks for the new information.
Their ancestry goes back to Charles Ervin who came from Ireland in 1784 and settled in Indiana as soon as it opened up for settlers about 1835. Charles Lemon Ervin (1842-1934) was the grandson of this Charles Ervin and the son of James W. Ervin and Lucinda Cummings.
Your Charles Lemon Ervin (1879-1930) would be the great-grandson of the original settler, Charles Ervin, who is buried at Leesburg Cemetery in Kosciusko County, Indiana.
His father, Charles Lemon Ervin (1842-1934), is buried at Rosedale Crematory, in Los Angeles.
