I'm searching for death information for

Edmond (aka Edward) Ronayne, b. Nov. 1832, Gurtrue, Cork, Ireland, d. between 1910 and 1916, Precinct 37, Boulder, Colorado, age 78+

Ellena Ronayne, b. July 1866, New York, d. before June 1916, Precinct 37, Boulder, Colorado (there were deed transfers at that time).

They had two daughters, Ruth, b. 1901, Chicago, Illinois and Rachel, born 1902, Chicago, Illinois. The family appears in the 1900 US Census in Chicago and in the 1910 US Census in Boulder.

Edmond was the author of a number of books about Freemasonry and other controversial topics; his name is frequently given as "Edward" (probably because he just said "Ed" to a census taker rather than "Edmond," i suppose).

I would be grateful for any information or pointers to where to find information. I have already searched every Colorado cemetery listing I can find along with public records that provide a search capability.

Thanks.
