Arnold Koller married a Betty (Elizabeth) Jane Koller. Lived in Milwaukee, Wisconsin. Arnold was a cook in the Army during WW2.
Other Koller's I remember from Milwaukee was Norma Koller, who had a son named John who died during the Korean War. Do not recall how Norma was related to Arnold, possibly sister (better known as Arnie).
They were unable to have children. Adopted a daughter named Nancy.
Arnold past away. Nancy had 3 children. Shane, Cassandra and Angel.
Shane was adopted by Betty Koller from her daughter Nancy and legally took the name Koller.
Shane has two childrenand a wife under the name Koller. Amanda Koller (wife), Arianna Marie (daughter), Shane Emmanuel, Jr. (son).
(obviously I am Shane. My grandmother is getting on in years and has a more difficult time remembering the past but I will see what I can do).
