Anton Beer was the son of Jacob Beer (Baer) and Katharina Richter. His sisters were Maria Beer Schröder and Rosalia Beer Kainz. The last name can be spelled Beer and Baer (pronounced "bear").

Anton's birth date and birth place has not been determined. He was 25 years old according to his marriage record at Solka on November 17, 1872, when he married Adolphine Wanisch. The Solka church books on microfilm #3791-3797, Book 3793-3 at Bukowina Institut in Augsburg do not have records to 1847 or earlier. A baptism record was not found in Radautz, Fürstenthal, or Gurahumora church books. The 1900 US Federal Census for Barton Township, Washington County, Wisconsin, gave Anton's birth date and place as Oct. 1845 in Austria. The 1905 Wisconsin State census for Barton Township, Washington County, estimated the birth year as 1845. The Archdiocese of Milwaukee Catholic Cemeteries records showed he died at age 88 on 3/31/1934. According to Paul Polansky's research, Anton was born in 1850 at Lichtenberg. Gertrude Siewi gedcom showed Anton Beer was born in 1847 at Glitt, Solka Bukowina.

Anton and his wife immigrated to America in June 1887 with their children Jacob, Pauline, Francis ("Frank"), Albert, and Maria. Their last name was spelled "Bär" on the passenger list of vessels arriving at New York on June 18, 1887 on the vessel Saale. Port of embarkation was at Bremen. They were on the same ship as their friends in Bukovina - the Wenzel and Catherine (Niga) Fastner family. They remained friends for many years as they moved around to Yuma, Colorado and Wisconsin.

On August 7, 1893, Anton declared an intention to become a citizen of the USA at Yuma County, Colorado. Between 1894 and 1900, the Beers moved from Colorado to the West Bend area in Wisconsin. According to John "Jack" Huber's May 20, 1996, letter, "Finally they reached the outskirts of West Bend but the townspeople wouldn't accept them because they were dirty with sand and mud. . . They did let them finally go to the north side of town (Barton) and settle. Surprisingly, Anton had a gold coin which he used to buy 10 acres of land with a small house and here they stayed. Also had a barn on it." The 1900, 1906 and 1910 census confirm the family lived in Barton Township, Washington County, Wisconsin.

Frank Koepke, Anton Beer, Old Residents, Dead. Former Barton Resident Died at Milwaukee on Saturday. . . . [obituary of Frank Koepke] . . . Anton Beer, 88, a former resident of the town of Barton and a pioneer in the Far West who trekked his way back to Wisconsin by covered wagon, died on Saturday, Mar. 31, after a brief illness at the home of his daughter, Mrs. Paulina Kircher, 1371 N. 58th street, Milwaukee, where he lived the last 12 years. A native of Austria, Mr. Beer migrated as a child [Anton was actually about 39 years old] with his family to Colorado, where a group of families founded the town of Yuma. A crop failure broke up the settlement, and the Beers came to Milwaukee by caravan. After a year at Milwaukee, Mr. Beer moved to the town of Barton, where he was a farmer until retirement. Survivors are two daughters, Mrs. Kircher and Mrs. Mary Mace of Pomona, Calif.; two sons, Albert of Milwaukee and George of Los Angeles; a sister, Mrs. Rose Schiedecker of Milwaukee; 16 grandchildren, and eight great grandchildren.
