Hi Barb, thank you for your help, that is so kind of you to help even though you're not related :)
It is interesting that her dad's name was Peter Olofson and her name ended up being Maria Jonsdotter and not Petersdotter? I'll look into this some more. As I mentioned, I'm working with the Swenson research center, so I'll see if they can explain this.
Many thanks! Carie
