Despite a few bumps in the road, she is remembered as being compassionate, loyal and devoted. After Henry’s death, she married her fourth husband Sir Thomas Seymour- an old flame. At the age of 36 Catherine was pregnant with her first child. She passed away shortly after from complications of childbirth. Sir Thomas was executed for treason less than a year later. Their daughter, Mary Seymour, left as an orphan, completely disappeared from historical record which led many to believe she had not lived past the age of 2.
