Welsh form of Ambrose. Emrys Wledig (or Ambrosius Aurelianus) was a Romano-British military leader who fought against the invading Anglo-Saxons in the 5th century. Tales of his life were used by the 12th-century chronicler Geoffrey of Monmouth to create the character of Merlin, who he called Merlinus Ambrosius or Myrddin Emrys.
People with the name Ericksen have a deep inner desire to use their abilities in leadership, and to have personal independence. They would rather focus on large, important issues, and delegate the details.
