In many records, - no reference is given.  When it comes to birth, marriage or death, in these records, - the source is usually LDS or the Mormon Church.  This source often gives the farm for connection. In m any instances I have changed this to the parish, a location that is easier to verify.

The material is not produced to make family albums, but to make it easier for most people to find relatives. In late 2009 the Hagerup webpage were registered more than 67.000 places all over the Net.  Thanks to all of you who give reference to my pagers.

My initiative came on my own family, a project that developed into the family of my spouse;  
the Hardi family. 

The main source for initial research on the family was in the publication: 
"Familien Hagerup i Danmark og Norge by Sofus Elvis, 
published at H. Hagerups Forlag in Copenhagen, 1902

Legatet til minne om Stiftamtmand Edvard Hagerup m/frue.

Hagerupgaarden i Bergen where Edvard Hagerup lived with his family

Gaarden Oevre Oeien in Alvdal, bought by Nicolai Hagerup, born 1736

The family Carlsen from Germany/Denmark

The painter Niels Hagerup b. 1864-1922 lived in the United States

Prime minister Francis Hagerup who handed over power in 1905 to Christian Michelsen
(Hagerup was afraid Russia taking over the Northern part of Norway if Norway became independent of Sweden.  In 1945 Russian troops took their time to leave after "liberating Finnmark".)

Gustav Vigeland was a friend of my grandfather Henrik Bergh f. 1879, and he was authorized to use "Wheel of life" as Ex-Libris in his time.  

There is a villain in every family.

The family name was protected, but as many people were allowed to use the name without repercussions, there is no restrictions today.  More than 50% of those that carry the name in Norway today, do not descend from the bishops in Trondheim or Kristiansand.  One Hans Sivert Christian Hagerup got elected to the Norwegian Parliament. He managed to irritate a legitimate Hagerup to the extent, - that a court order forced him to change his name. 

As so many individuals have taken the name, it could be a sign of "someone one does want to be related to"?

Other significant sources in looking for ancestors;

Sweden still has some distance to go before they  have useable data, but there is what they have. They have data, but you have to pay "an arm and a leg to get access" to useful data.
