This appears in the Swedish-language Wikipedia article about Herman Wrangel. She married Herman Wrangel in 1612.
From Wikimedia; I made the background uniform deep gray, leaving her, her dress, and her insignia intact, before filling in shadows slightly in an attempt to bring out her maroon-black skirt. The original background color was somewhere between the deep gray seen and a lighter gray that may be due to fine dust deposited on the portrait. The area under her left tabbed sleeve was indistinguishable from the background so I left the dusty gray alone where the tabbed sleeve would come back around her arm.
