Adlersparre is a Swedish noble family, which is descended from the mayor of Bogesund (which is now named Ulricehamn) Christopher Andersson, who was active during the earlier half of the 17th century.
The name Oskarström is not named after the Swedish kings Oscar I or Oscar II but bookkeeper Oscar Bjorkman who was born in Ulricehamn and who in 1844 bought a piece of land with waterfalls by the Nissan river.
