Yes, those are them. I didn't have a date or place of death for either of them, just after 1900 in Wisconsin for him and before 1900 in Wisconsin for her, so I'm glad to have that information now, thank you :)
Lars Christian was born in Koldby, Thisted to parents Lars Larsen Sund and Kirstine Christensdatter. Inger Marie was born in Hørdum, Thisted to parents Jens Nielsen Smed and Else Larsdatter. Her church records state that she was born 2 July 1829 rather than 3 July. I've gone back a couple more generations on her pedigree, but I only have the parents info for Lars Christian and the baptism records for him and his siblings. I'd be happy to help you with any information on his pedigree if you need it. I don't know how familiar you are with Danish church records and I don't mind doing a little hunting for more of his line. And of course you're welcome to any info I have on Inger Marie's line. I have church records for all her siblings including marriages and children for most of them, plus church records going back to her great grandparents in the early 1700's. Let me know if you're interested and I'll be happy to help you out.
