Hello, I am familiar with only one family named Otto settling in Lac qui Parle Co., MN, and Have done extensive research there. If you can connect me to a time and township, I can look further in my records.
That family, William Otto m. to Alvina Borchardt who was b. on Sept. 27, 1904 at Bellingham, MN d. in Nov. of 1988, possibly in IL. They had one infant and were living at Plainfield, IL in 1952. No further information is currently known.
I do have a rather extensive file of the Otto families that settled in Carver and Nicollet Counties, MN, tho. If you are connected to those families, I can possibly be of some assistance.
One family is the Henry Otto and Friedrike Dallmann family from Pommerania who settled in Nicollet Co., MN Henry died on Oct. 8, 1913 and Friederike, b. Apr. 27, 1853, d. after April of 1940. They were married at Nicollet Co., MN on Mar. 22, 1872. Children were: Albert C., Wilhelmina (Mrs. John F. Daak), Martha (Mrs. August Daak), Anna (Mrs. Albert Deide), Henry F., Jr., Edward, Frederika (Mrs. Julius Duesterhoeft), Emma (Mrs. Henry Duesterhoeft), John, Carl, Edna (Mrs. Herman Bunke), Herman, and Marie (Mrs. Fred Dummer).
A second family was Conrad Otto who m. Sophie Doepke and were the parents of Emilie (Mrs. John Quast). The family possibly lived and is buried at Brownton, McLeod Co., MN.
Emily and JOhn Quast lived at Renville, MN and were the parents of Elizabeth (Mrs. Fred Martin), Adella and Walter.
Third, Henry Otto who m. Mathilde Gill and had a dau. Martha (Mrs. Joe Heimerl). Martha and Joe lived at Winsted, McLeod Co., MN and had the following children: Edward, Agatha (Mrs. Bernard Habisch), Elizabeth (Mrs. Alphonse Hartmann), Mathilda, Leo, Cecilia (Mrs. Henry J. Wemhoff), Leonard, Andrew, Joseph, Benedict, John, Roman and Louis.
Fourth, Henry Otto who m. Sophie Kappel and had a dau., Marie Magdelyn (Mrs. John P. Karels) which is where my family and my interest comes in. John and Marie are the parents of: Mary Ann (Mrs. William Neumann), Delores (Mrs. James Provincher), Ronald, Gerald, Jack, Yvonne (Mrs. Jack Barrett), Susan (Mrs. Glenn Hagen), Jean Rose and an infant.
Fifth, There was a Willie Otto who d. about 1895 m. to a cousin, Mary Pillatzke, b. in 1867 and d. in 1951. They had a dau., Frances Otto, b. and d. in 1895. The family lived at Delano, MN for a time. Mary's parents were from Germany and settled at Delano, MN. She had 8 siblings, that I know of, but I don't have much information beyond their names.
Sixth, Joachim Otto, dates and wife unknown, had two children; Dorothea (Mrs. August F. Schulz) and William. The Schulz family had a son, Otto who was born, June 7, 1876 at Camp Release Twp., Lac qui Parle Co., MN, but I have no indication that the Otto's lived there. August F. Schulz and his wife, Dorothea were born in Brandenburg, Germany, and both died in the U.S., but where is not known. They had 6 known children.
If any of this connects to your family, please let me know. I also will be happy to take any info. you are willing to share and put it on my data base, in case I come up with any further info. related to your family.
