Wm. Winkelmann, late owner of the Springfield Roller mill, has concluded to join the party, who in a couple of weeks will make a pleasure and sightseeing trip to the state of Washington. He had at first intended to go to Europe. (New Ulm Weekly Review, Wednesday, April 9, 1890, Volume XIII, Number 13, Page 5)

Mr. William Winkelmann, from New Ulm, Minn., who was in the lime business at the Great Cottonwood and also proprietor of the Roller Mill at Springfield in that state, came west and after much looking around both here and in the Pacific Coast States has decided to become a citizen of Helena. He has found limestone at Ellison, thirty miles from Helena, which he says is not excelled in the state of Montana. Mr. Winkelman has bought the limekiln there. We wish him much luck in his undertaking, and hope the contractors will do business with him. An acquaintance of 32 years enables us to speak highly of him. – Montana Stasts Zeitung.

The death of Mrs. Alvina Gley, wife of Friedrich Gley, occurred last Friday morning at about eleven o’clock. She had been sick for some time, and being an old lady her death was not unexpected. Mrs. Gley was born in Friedland, Mecklenburg-Strelitz, June 29th, 1821, and was consequently in her seventy-first year. At an early age she was married to her present husband, and in 1866 they came together to America. New Ulm was their first destination. Here they remained continuously and gathered to themselves a large circle of friends. The result of their union was four children, only two of whom, Fred C. Gley and Mrs. Wm. Winkelmann are now living. To these and to the surviving husband the Review extends its sympathy, knowing that it will be shared by our citizens in general, by whom the deceased was always held in respect. The funeral was held from the residence Sunday afternoon, Rev. Albrecht officiating, and was largely attended. (New Ulm Weekly Review, Wednesday, April 22, 1891, Volume XIV, Number 16, Page 5)

Dr. Koehne in Custody. Charged with the Murder of Policeman Winkelmann on the Night of July 3rd. The Arrest is Made at Lamberton on Warrant Issued by Justice Brandt. When Lodged in Jail, the Prisoner Breaks Down and Cries Like a Child. The Preliminary Hearing Postponed to Thursday, Nov. 7. About Thirty Witnesses Have Been Summoned to Appear at that time. The citizens of New Ulm were startled last Thursday to learn that Dr. August Koehne, a veterinarian who is well known in all this region, had been arrested upon a warrant issued by Justice Brandt, charging him with the murder of Policeman Albert Winkelmann on the night of July 3rd, last. The warrant was issued at the instance of the county attorney and upon the complaint of Wm. Winkelmann, father of the murdered man, who came here shortly after the murder from Helena, Montana, and has spent the greater portion of his time since then in looking up the case. It will be remembered that Albert Winkelmann was shot in a dark and lonely part of the city on the night mentioned and that his body was not found until the next morning. There was every evidence that some one had laid in wait for him, knowing his beat, and the tramp theory did not gain credence. People naturally looked to other quarters for the source of the crime, and there were many rumors implicating Koehne, as he was known to have been an enemy of the policeman and is alleged to have made threats against him, even on the night of the murder. The fact that even on the very next day he left town with his family, pawning a revolver before he left, added to the prevailing suspicion, and the authorities were strongly tempted to make the arrest at the time.

They concluded to wait, however, and keep him under surveillance. This was evidently done with some success, for on Wednesday County Attorney Davis advised Mr. Winkelmann to have the warrant issued and he did so immediately. It was placed in the hands of Sheriff Anderson, who took the night train for Lamberton and made the arrest that very night. A hearing was to have been given the prisoner on Thursday but he asked for time to secure witnesses and an attorney. This was granted him and Monday was fixed as the day for the examination. When taken to jail Koehne broke down and shed tears. He insists on his innocence, of course, but finds it a difficult matter to keep up courage. On Monday a good-sized audience collected at the old court house to hear the examination, but were disappointed when Attorney Baasen, in behalf of the defendant, asked for a stay of ten days and it was granted. He alleged that there were a number of witnesses that could not be reached before that time. The hearing was accordingly postponed to Thursday, Nov. 7. Koehne is a well known character in these parts, having acted as a veterinary surgeon for a number of years. He claims to have been an alderman in Chicago at one time, and also says that he is a son of the noted Low German poet, Fritz Reuter.

Miss Ida Winkelmann died Friday night after a brief illness. A postmortem examination on Saturday proved that death was caused by obstruction of the bowels. The deceased was a daughter of Wm. Winkelmann, the well-known Cottonwood citizen, and was in every way an estimable young woman. (New Ulm Review, Wednesday, August 3, 1898, Volume XX, Number 32, Page 8)

New Ulm, Minn., Feb. 25. – (Special.) – William Winkelmann died last night at his home in this city, of heart failure, aged seventy-one years. He leaves a wife, two sons and two daughters. (The Saint Paul Globe, Sunday Morning, February 26, 1899, Volume XXII, Number 57, Page 1)

Obituary. At the ripe old age of 70 William Winkelmann, one of the oldest of New Ulm’s many old settlers, died last Friday evening (February 24, 1899) at his home in this city, as the result of heart failure. He was sick but a few minutes and breathed his last while his son Henry was up town after a physician. Mr. Winkelmann was born in Mecklenburg, Strehlitz, Germany, in 1828, on the 29th day of July. In 1853 he came to America and settled in Chicago. The following year he accompanied the colony that started out from that city to form a settlement in the then distant and undeveloped West and which finally selected the present town site of New Ulm as a suitable place and formed the nucleus of this beautiful little country metropolis. He then took a claim in Cottonwood township and engaged in farming. In 1886 in company with others, he built a flouring mill at Springfield which he sold in 1890 when he went to Montana and embarked in the lime manufacturing business at Helena and Elleston. After four years in the west he returned to New Ulm and has since made this his home, being in the lime business here at the time of his death. In the Indian outbreak which occurred at New Ulm in its early history Mr. Winkelmann commanded a company and there got the title of captain. He was married here in the 50’s to Carolina Dittbenner and five children were born to them, two daughters and three sons. The widow, one daughter, and two sons survive him. Eleanora Gerber and William are residing in Montana, while Henry is living here. Funeral was held Monday afternoon from Turner Hall where Capt. Steinhauser addressed those who were gathered around the bier. At the grave Chas. Brandt spoke on behalf of the A. O. U. W. to which the deceased belonged.
