Gustav J. Seaquist (name in USA) was born 5 Sept. 1885 in Sweden.
He died in Ramsey county, Minnesota Oct. 13, 1973.

at findagrave.com it says this for his birthplace and parents:

Gustav was born in Wexsjo, Sweden Parents: Anders Seaquist & Matilda.

He emigrated some time about 1904, according to the 1930 census.

Someone helped me find this possible family for Gustav.

Parents:
Anders Jonsson born 12 April 1848
Mathilda Johansdotter born 24 Sept. 1847

Anders and Mathilda married 28 March 1868.

They lived in östra Jät parish at a place called Knutsagård. That is in Kronoberg. Near Växjö.

Maybe emigrating from Jät in 1903? 1904?
#3 30/4 Johan Gustaf Andersson, arbet, born 1885 5/9 fran J. Knutsagard p 249 to N Amerika

I think it is possible that Johan Gustaf Andersson became Gustav J. Seaquist. I'm not sure why or how, but the parents' first names match, the birth year matches, and the Wexsjo place is probably Växjö.

He has several siblings, I wonder if they are on any census in Sweden before 1903 or 1904?

I also wonder if there is a way to trace any relatives that might still be in that area?

These might be his siblings:

1.
Andersson Jonsson, Jon August
Son (unmarried man)
b. 28 Feb. 1870 in Nöbbele parish, Kronobergs län (Småland)
Emigrated 6/25/1891
from Östra Jät, Knutsagård, Jät, Kronobergs län (Småland)
to Denmark

He must have come back from Denmark, and then left the parish again:
Jon August Andersson, worker, born 28 Feb. 1870 from Jät, Knutsagard p 249 left the parish 21 March 1903 to Tanum, Gotesborgstan

2.
This family was living at Jät, Knutsagård in the 1890's,

I think he became Gustav J. Seaquist once he came to Minnesota.
