Parents of Louis J. Carlson (Lars Johan Karlsson) 29 Mar 1870 Sprgnarden,Algaras

Looking for parents of Louis J. Carlson, also known as Lars Johann Karlsson, b 29 Mar 1870 Sprgnarden, Algaras, Sweden.
He migrated to USA around 1887; unsure if parents immigrated.
He lived in the Boston, Massachusetts, USA area and died 14 Mar 1947 in Quincy, Norfolk, Massachusetts, USA.

His father may have been Carl August (Johanson) Carlson b 1845 d 1924.His mother may have been Augusta Johnson
This is the only information the family has.

Louis married Ida Isabelle Russell in 1917 in Foxborough, Massachusetts and they had the following children:
Fred Porter 1919-1996
Esther Ida
Frank Louis

I am doing this research for Frank Louis Carlson's daughter.

Any help appreciated.
