Henry Theodore Seiderman, 84, died Wednesday afternoon at the home of his daughter, Mrs. P. F. Barkis, following an illness of several months. A requiem high mass was conducted Thursday morning at eight o'clock in St. Joseph's Catholic Church by Fr. James Franchi and burial services held in the afternoon at 2:30 o'clock at the Catholic Cemetery.
Born August 1, 1856, in New Braunfels, he grew to manhood there and in sections of West Texas and New Mexico. In 1880, he worked on the Simpson and Carter ranch in Mexico and worked there at the same time as Billy the Kid. One time Mr. Siederman credited Judge Roy Bean with befriending him by defending him in a trial.
In 1883 he was married to Miss Theresa Simon, who survives him. They made their first home in New Burlin. For 59 years, Mr. Siederman followed the trade of a blacksmith, which took him to many sections of the state. During the last world war, he worked on a dredge at Galveston. He came to Pecos County some 16 years ago with Mrs. Siederman and they lived in Fort Stockton, Irvan and Girvin during that time. He was a devout member of the Catholic church and took an active and faithful part in its work.
