I am researching my 2nd great grandfather, Nels (Olson) Burkum, born 02 Jun 1831 in Børkjo, Lærdal, Sogn og Fjordane, Norway. He came to the U.S. circa 1861, where I believe he married Maria Jensdotter from Luster, Norway. Nels's sister, Sinneve Burkum (born 24 Dec 1836), and her husband, Anders Hendrekson,(born abt. 1832), came to Crawford County from Børkjo, Lærdal, Sogn og Fjordane, Norway circa 1857. They changed their names to Andrew & Susan Henderson, and are buried in Freeman Township. I am looking for other descendants or who are familiar with the family.
