There is an article that describes the patronymic naming system observed in the following tables but simplified: A child’s surname came from the father’s first name. If you had a daughter you would add – datter to the end of the father’s firstname, if you had a son you would append  – sen or –son, – søn, the meaning is the same) to the father’s first name. Sometimes the name of the farm was used as a 3rd name not so much as a surname but as an address identifier. The following table is translated from parish census records : Hemnes Church in Nordland, Norway and from Carl-Anders Olsson online and the Digitalarkivet at the University of Bergen online. The tabular presentation that follows is a simplification of statistical information contained in the book of farms: Hemnes Gård og Slekt. You can inspect a copy of pages 567 to 572 (Straumbotn) from that book. Keep in mind that the contents of the book of farms is itself a transcribed version of original handwritten ledgers for farm number 89 in the book. Note: The Leilending (leaseholder) didn’t own the land but was granted it’s use through a lifetime lease contract.  The Strombotne relatives were leilending (tenant) farmers. See background information on Norwegian farms. The leaseholder was generally a couple and the lease was good for his, or her lifetime.  The biggest threat was the death of either the husband or the wife, since there had to be a “couple” on the farm; consequently, remarriages were very common in the leilending system.  In most cases a leilending couple could let offspring inherit the land, but a new lease contract had to be registered. 

As families grew, Strømbotten farm would be divided to accommodate. A secondary numbering unit (‘bruksnummer’ with the abbreviation ‘bnr.’) with a name commonly appended was utilized for such property. As such Mons Pedersøn allowed for his two daughters and their families by dividing the farm into 2 units Bnr. 1 Straumbotn and Bnr. 2 Straumbotn in 1726. Eventually there would be additional units added:  Bnr. 3 NYGAARD in 1892, a new parcel from Bnr. 1 Bnr. 4 ØVRINGMO in 1899, a new parcel also from Bnr. 1 Bnr. 5 NYMOEN in 1911, a new parcel from Bnr. 2 Bnr. 6 BJERKE in 1948,  a new parcel also from Bnr. 2 and Bnr. 7 SJELMO from Bnr.5 in 1951

The 1900 Census for Strømbotten  Farm lists Units 2 and also Unit 1, 3 . In the 1900 Census, Kristoffer Olai and his daughter Pernille have adopted the farm name for their last name as per custom trend. The change to a fixed family surname  began in the early 1800’s and was widespread by about 1900. The use of a fixed family name was made compulsory by law in Norway in 1923. As a result of this change, many began using their patronymic name as their fixed family name; others chose their farm name as their permanent family name and thus the name — Strømbotne or Strombotne.
