Cornelius P. Sheehan, pioneer rancher of the Sweetwater country, passed away at Bishop Randall hospital Wednesday night ending a long and eventful life of ?? years. He was one of the few last [?] who settled on the Sweetwater in the homestead era following the days of the big cattle outfits. He acquired a good herd and was a successful operator. He was born at New London, Connecticut April 16, 1862. He grew to maturity there and at the of 23 struck out for himself to make a place in the great west. Colorado was the center of attraction those days with Denver fast becoming a mining and livestock center. With Billy Johnson and brother Dennis the trio sought adventure and life in the open. A trail herd was moving into Wyoming and they got a job. It took them down the Platte and onto the Sweetwater. It was the days of the 71 ranch with its scores of riders, men coming and going, and a job was easy to be had. The country was wild, bad men held up stages and robbed banks. Outlaws stole horses and the men with the longest hemps got the maverick calves as their foundation herds. It was a picture of life on the range those three young men had something to write home about. When the 71 Ranch, one of the largest outfits in all the west as it grew under the wise management of John Clay, reached a place where it was realized that the changing conditions made it no longer sensible, with nesters cutting the range as a gridiron with wire fences, to run cattle on the unlimited range areas, Sheehan like other young men of his day had to seek a job. He worked for Tom Sun whose ranch holdings were near DevilÕs Gate on the old Oregon Trail on the Sweetwater. He could not have found association with one who knew more of the real West than Sun who had come up thru the scouting days of Jim Bridger, Kit Carson and had settled down to make a home in the livestock industry. 

Con and his brother Dennis were inseparable. They filed on adjoining homesteads farther up the river. Taking advantage of the homestead law and gathering a bunch of cattle, together they increased their holdings by buying up filings when proved up on and finally developed a livestock spread that was one of the best on the Sweetwater.

In June 1905 he was united in marriage to Miss Cathryn Sheehan of Dixon, Wyoming, a small settlement on the Colorado line in the Little Snake River valley. To them a daughter, Maxine, was born. As age came on Mr. Sheehan disposed of his ranching interests and moved to Lander. For nearly a year he has been a patient at the Bishop Randall hospital, suffering from a serious illness. The end came in peace, Wednesday, January 14. Funeral services were held Saturday morning at the church of the Holy Rosary, the Rev. John Marley in the ceremonies of high mass performed the last rites for the dead. The church was filled with many old time residents who came to pay respects to their friend. He is survived by his widow and daughter, Maxine, who has carried forward the ranching interests since the indisposition of her father. Burial was at Mt. Hope in charge of the Benson-Coolidge Company.

Cathryn died from injuries sustained in an automobile collision southeast of Loveland on Saturday, 5 August 1944. She was 66 years, and she died at Loveland Hospital.
Mrs. Sheehan had lived in Loveland about three years coming from Lander, Wyoming. She owned a number of riding and racing horses, which she kept at the Loveland fairgrounds. Her body was buried in Rose Hill Memorail Park, Whittier, California, where near the grave of Maxine, a daughter, who died on Aug 12, 1941).
