Emma Marie Iverson, born December 30, 1894 in Canada, died in Kings County on August 12, 1980. Father's surname Caron, Mothers maiden name Castonguay
They are both buried in Calvary Cemetery in Madera County.
There is also an Alfred J. Iverson, born July 23, 1930, and died February 3, 1956 buried in the same cemetery - I tried to verify he was the son of Otto and Emma, but have not found proof of that yet. He was shot down over Tokyo while serving in the Korean War. There was a brief article that referred to him as Joseph Alfred Iverson
You can see the gravestone's herehttp://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GSln=iv...
Raymond Otto Iverson, born February 7, 1923 in Massachusetts, died in Madera on February 10, 2009. There was only a brief death notice that did not list any relatives.
Raymond married Alene C. Stephens in Madera County on November 11, 1966. She was also listed as Alene C. Mcalvain. I do not know if they had any children.
I was unable to find any more information about the daughters. I tried to find the family in 1940, but they may have moved to a different area in Madera County. You can only browse the census right now, and not search, as it is not fully indexed. When it is, you will be able to tell if Alfred Iverson was their son.
You might repost your query with the death date for Otto and see if someone local can look for an obit.
I am not related.
