I realize that this thread is 7 years old, but I wanted to reply with what I know.
My name in Tim Tyren.
I'm the great-grandson of Maria Göransson and Arvid Johansson Tirén.
Maria and Arvid immigrated to Aitkin County, Minnesota, United States in 1901.
They traveled through Canada.
They changed the spelling of the family name to Tyren at that time.
