I found Nicholas Everling in the 1930 US census for Phillips County, Montana by using ancestry.com. He is living on a farm which he apparently owns and is listed as a farmer, age 41 years (should have been 51 years). He is single and has a man living with him named Robert Schimmel, an immigrant from Germany, age 45. They are both listed as farmers.
I also found a death record extract for Nicholas Everling. The Montana Death Index lists him as born about 1882;died on 3 Nov. 1952 in Montana. There was no place listed. Apparently a death record can be purchased from the state of Montana.
