HI, I hope this hasn't been too long since you posted your message. My husband is a descendant of Soren Pedersen (Samuel Petersen) who was one of Margarethe's sons from her first marriage, but until we were in Denmark and found information on them all emigrating we didn't know anything about her and Jens Marcher, we knew they had married, but didnt know they had lived in Manti.
We have been interested in any information on her after coming here, or any pictures that anyone might have.
Would be glad to share any information we have, but it would be on the Pedersen's not the Marchers.
Thank you for any help you may be able to give us.
