Do you have any info on the Luehring side? I saw a notation that in the Goodhue county History on page 534, there is something mentioned in 1878 about a Mary Luhring. I will try to get someone from Goodhue to find it for me. Btw, my grandfather was Wilhemina's brother. He married a Catholic girl Ella Kelly, and according to the family, was disowned by his sisters until one of his son's died in WWII. Hopefully they all made up by then!
Thanks, Barbara
