Jensen was born in Würzburg as the daughter of the German writer Johann August Moritz Bruehl (1819–1877).
In 1865 she married the poet and historical novelist Wilhelm Jensen in Vienna, whose portrait she painted.
The couple first lived in Stuttgart, and then moved to Kiel where their youngest daughter Katharina was born (she later married Ernst, Prince of Saxe-Meiningen, and had six children).
Marie is buried there with her husband under a gravestone by the artist Bernhard Bleeker next to the grave of Emil Lugo.
