Lindström, Olof b1859-1862. Utv 1867/1868 ?

[Sten Tegfors]

För USA väns räkning söker jag hjälp att hitta denna man: John Theodore. Dom tror att eventuellt John i nedanstående familj kan var rätt man.  
Någon som kan hjälpa mig hitta vilken församling dom utvandrade från och sonen Johns födelsedatum?
 
The John Theodore Thornquest I am searching for was born in December of 1859 or 1860 or 1861 or 1862 but in December of one of these years.  
He married 19 May 1882 in Ramsey County, MN to Emma M. Olson.
 
In the 1885 and 1895 census they are living in Ramsey County, MN. In the 1900 census they are living in Tacoma, Washington. In the 1910, 1920 and 1930 census they are living in California. He died in 1935 in Portland, Oregon while on a trip. Buried in Riverside, California.
 
He may have lived in the Delano, MN area or the Watertown, MN area when he first came to MN in 1865 or 1866.
 
I have found a family in the 1870 census of Watertown, Carver County, MN, Pg. 301B.

Mary Lindstrom age 34 born Sweden
John Lindstrom age 10 born Sweden

It appears they immigrated between 1867 and 1868.
