It is possible that is the same man. Or not. Although the birthday is a month different and the name is a little different.
Maybe finding the family could help, especially if you have a picture of him.
His daughters Mrs. Harry Swanson (?), Mildred Anderson and Alphie Anderson were all still living in Stillwater. Maybe there is an obituary for his wife, at a later date when she died, and for his daughters in Stillwater at the Historical society there. I gave you that address earlier.
For the other daughters:
Mrs. Elmore Olson of Chatfield, Minnesota,
The historical society for her would be
FILLMORE COUNTY HISTORY CENTER
202 County Road 8
1 Block East of Jct. US 52 and County Road 8
Fountain, MN 55935
Executive Director: Debra Richardson www.fillmorecountyhistory.wordpress.com
The town of Chatfield also has a historical society
Chatfield Historical Society
President: Nancy Mc Mahan
Chatfield, MN 55923
Because I think Chatfield the town is right on the line between two counties, Olmsted and Fillmore.
I think I found the death for the son-in-law Elmore Olson in Olmsted county, on the Minnesota death index.
OLSON, ELMORE S.
Date of Birth: 20 Aug 1898
Place of Birth: MINNESOTA
Mother Maiden Name: LARSON
Date of Death: 28 Aug 1962
County of Death: OLMSTED
Maybe an obituary for him would give children's names.
Chatfield is on the line by Olmsted county.
