Johan Gabriel Oxenstierna was born at the Skenäs estate, by lake Kolsnaren (now in Vingåker Municipality), in the province of Södermanland [REF].
Although Oxenstierna's writings were not published until after he moved from Skenäs and started working, he did write a Diary between 1766 and 1768, which was published in 1965 by Bokgillet publishers in Uppsala under the title Ljuva ungdomstid: Dagbok 1766-1768 (Sweet Time of Youth: Diary 1766-1768) [REF].
