To begin with, Franz was born in the small village of Ollmuth, in the Rheinland Pfalz of today's Germany. At the time of his birth and childhood, this village was within the Kingdom of Prussia; then ruled by Frederick William IV of the House of Hohenzollern. The concept of the state of Rhineland Palatinate is a modern construct, dating to after World War II, in about 1947, depending on which event in its formulation you consider to be the definitive moment for what is now a political state, occurred. (Rheinland Pfalz = German & Rhineland Palatinate = English) His parents were Peter Endres (6 Mar 1813 - 18 Jul 1897) and Margaretha Klein (3 Feb 1816 - 18 Jul 1897). Franz is part of a family which emigrated from what is now western Rhineland Germany to the Midwest in the 1840s, and very prolifically populated the rich farmlands of northwest Dane County, and some of the surrounding area in adjacent counties. He and his wife had fourteen children that we know of, but it is almost a certainty that there were others whose births were not put into the record.

_____His obituary reads thus______

Frank X. Endres died at his home, 1206 Chandler Street, on Sunday afternoon after an illness of sixteen months of liver and kidney trouble, though he had been confined to his bed only nine days. Franz Endres was born in Ollmuth, (present day Germany), 8 Jan 1843. He came to America in 1859 and located in Dane township, where he lived till 10 years ago when he moved to Madison. He was married 26 May 1868 to Elizabeth Karls, who survives him. There were born to them ten sons and four daughters. Two of the daughters died in infancy and two sons after they were grown to manhood. There are now living Matt, of New Royal, Ohio; Alphonse of Milwaukee; Frank, Joseph, Albert and William of Madison; Gregory, who is a student at St John’s university, Minnesota; Mrs Gerhardt (Margaret) Ripp and Mrs Matthew (Philomena) Doll, both of Madison. All the children were present at the time of his death except Matt, who had returned to his home in Ohio after a visit with his father last week. The funeral will be held at St James church at 8 o’clock tomorrow morning, Rev Joseph M. Koester officiating. The bearers will be Frank Gross, John Dohm, J. Feiler, Joseph Little, M. Schallenberg and B. Kleinheinz. Interment will be in Calvary Cemetery.
_____
B. Kleinheinz is probably Bruno Kleinheinz, a grocer and saloon owner in the neighborhood listed in the 1909 Madison Directory. He lived at 702 S Park St.
Similarly, M. Schallenberg is most likely Martin Schallenberg, a shoemaker working at 620 University Ave and living at 1110 West Washington Ave in 1909.
Joseph Little (spelled Littel in the directory) was a carpenter working for the Kessenich firm, who lived in the same neighborhood as Franz, at 1335 Mound Street. Further, Franz's son Frank was married to Catherine Kessenich, so there may be a another connection there.
Frank A. Gross was a carpenter living at 1201 Mound St.
John Dohm was a partner in a firm called Burmeister, Dohm & Bibbs, and lived at 1211 Mound St. After exhaustive digital searching in a pdf copy of the directory, I found that this firm were "Land Agents."
