As a result of World War II, most bygdelags did not mean in 1942 and were inactive for many years.
In 1983 after a period of 40 years, Solorlaget was reactivated and it again an active bygdelag with a current membership of about 400. It is a bygdelag for people whose ancestors came from the Solor region of Norway.
At the time of reactivating, there was no lag focused on the many other areas of Hedmark, so the Solorlag also began collecting research materials to serve members with roots in Nord-Odal and Sor-Odal, Kongsvinger (Austmarka), Eidskog (with Vestmarka), Elverum and surroundings, Loten, Stange, Romedal, Ringsaker, Nes in Hedmarken, Trysil, Tynset, Rendalen and Engerdal. Many members whose ancestors originate in other areas of Hedmark are attracted to the programs and research materials of the lag. The lag has members from the United States, Norway, Sweden and New Zealand.
