My family’s Swedish. We came destitute to America and moved to Minnesota. It wasn’t safe to be a Swedish person, we didn’t outwardly say our names because we didn’t want to give away that we were immigrants. So when my great-great-grandparents put my great-grandparents into school, the 2nd grade teacher offered us a more Americanized spelling of our last name. That way if they hid their accents better they could be considered for jobs that would make a living wage.
When I was a baby, my whole family had a vote on how we wanted to spell and say our last name. We ended up keeping the American spelling for ownership but used the original Swedish pronunciation. – Bryan
