I am looking for any info regarding Nis (aka Ness) Mortensen who married a Christina Kliver (Cliver) in Lansingburg, NY in the 1870's and their daughter Annie K. (Kristine?) Mortensen, who married Marus (Marius?) Jensen in St. Paul, Howard County NE, then later married Niels Sorensen, in 1896, also in Howard County NE. I have to write for more documentation, but have marriage records and SS card app for Marus & Annie's son, Jens Pete Jensen. I descend from their daughter, Martha K. (Kristine/a??) Jensen. She was my ggrandmother, paternal. Happy to share what little that I have too! Thank you for any help!
