Here I will present the information I have about the family of my great-grandmother Kristine Benedikte Eriksdatter. She was married to Ole Nilsen, so since this is the genealogy cite for my maternal grandmother, it will be called Nilsen.
The family history of my great-great grandfather - Erik Nilsen - is the reason I start this cite. I guess his patronymic name was the reason why the oldest one of his children used Nilsen as a family name, while the youngest - Søren - used Eriksen or Erickson after his father's first name.
So, this is a cite for information about Erik Nilsen (1812-1891), his wife "Kjerstine" (1839-1910) and their ten children:
Nils Chrisitan, born July 22nd 1858
Johan Adolph, born August 17th 1860
Conrad Bertinus, born June 16th 1862
Kristine Benedikte, born December 15th 1863
Anton Marius, born August 2nd1865
Carl, born February 24th 1868
Anna Rebekka, born January 25th 1871
Peder Olaus, born May 7th1874
John, born March 8th 1879
Søren, born September 9th 1881
