These are recently living people my stepchildren want to know about. Leora Zabelle Brunswick was b in Mankato, Mn about 1930. Her brother was Leonard and sis Jayne b abt 1922. Their mother, was Florence and father's name not known but thought to be German-Jew. He died and Florence lived with or mar Eric Olson in Superior, Wisc abt 1946 & lived at Two Harbors, Mn until 1961. The family never kept in touch and the descendants want to know more about the maternal side. I am trying to get them started. Thanks.

No connection with my Brunswicks, but I found some mentions of this family in ancestry:com

In 1920 Leonard, Florence and Leonard Jr. Brunswig [very common varient on this name] are living in Duluth MN.
They are all listed as having been born in New York
I was not able to find them in the 1930 census, but Leonard Jr and Jayne show up in the Mankato High School Yearbook Record 1936.
