Seeking information on Jack and Clara Gage who lived in Brainerd, MN.

Jack (my uncle) died trying to save his four sons during their house fire. Jack's wife, Clara, lived long enough to give birth to their fifth child and only daughter, Helen.
Helen survived and was raised by her maternal grandparents in North Dakota.

Believe this fire was between 1925 and 1930. Have not located Jack Gage's birth index record, but know he was born in Winona, Winona Co., MN, son of Albertus (Albert) and Sarah (Sadie) Ora Gage. Jack was born in very early 1900's.
Assume that Jack, Clara and sons are buried in the Brainerd area.

Appreciate any/all info. Thank you.
