Adelborg is a Swedish noble family, which consists of two different lines. The older main line is descended from the burgher and brewer in Gothenburg Anders Eriksson, who died before February 1688. His son was the customs controller in Helsingborg Lars Andersson Borgh, who died 1719. His grandsons were the adjutant and later Captain Eric Otto Borgh (1741–1787) and his older brother Johan Borgh (1736–1805), who were ennobled 13 September 1772 at Stockholm Palace by King Gustavus III of Sweden with the name Adelborg, and were introduced 9 May 1776 at Riddarhuset as noble family number 2090.
