There were Etchells in the Lafayette, CO area. I found this wedding announcement in the Lafayette News dated Oct 5, 1901:
"Married--Tuesday, October 1, 1901, at the residence of the bride's parents by Rev. Terrill, Mr. James Etchells and Miss Lizzie Bell, both residents of Lafayette. Miss Maggie Reese was bridesmaid and Mr. James Bell was best man. The newly wedded couple spent their honeymoon taking in the sights at the carnival. They have taken rooms in the Goodhue building for the present. We wish them a life of happiness."
Also, the Lafayette cemetery lists Samuel A. and Hermina G. Etchells.
Good luck!
