Hello and welcome from an Iowa Girl!
I, too, am a GD of Swedish immigrants. As a child when they started talking in Swedish I knew they were planning something special for us! My mother did not speak English when she started kindergarten; learned the language and taught the rest of the family how to speak.
Have a great time searching for quilts here in USA. I just Googled "USA quilt museums" and came up with some excellent sites for you to investigate. This one has a lot of info.
