Laura is the wife of Clint Barton/Hawkeye. She is kind, gentle, friendly and supportive. She lives at the Barton Family Farm with her (and Clint's) children, Cooper and Lila. Later, she gives birth to a third offspring, Nathaniel Pietro, named after Natasha Romanoff/Black Widow and Pietro Maximoff/Quicksilver.
Laura are her family are not in any goverment files, which is why the Barton Family Farm is used by the Avengers as a place to hide and lay low.
