On the afternoon of June 14, 2007, Flag Day, Jefferson National Expansion Memorial hosted a naturalization ceremony for 66 new American citizens. The affecting ceremony was highlighted by the presentation by Superintendent Peggy OâDell of copies of the new brochure entitled âNational Park Ownerâs Manual for New Citizens of the United States of Americaâ to each of the participants. These 66 people were the first new citizens in the United States to receive the brochure. Participants were surprised to learn that Director Mary Bomar, like themselves, was a naturalized citizen. Mary Grace Ford, an employee from nearby Ulysses S. Grant National Historic Site, a naturalized citizen from Italy, was recognized at the ceremony. Superintendent OâDell expressed the hope that âsome of you will not only take the opportunity to visit national park areas across the country . . . but may also let the example of Mary Bomar and Mary Grace Ford inspire you to serve your country, as a government employee or as a volunteer at one of the nearly 400 sites across our nation.â New citizens who took the oath of allegiance to the United States in the rotunda of the Historic Old Courthouse included men and women whose countries of origin included three South American and four African nations, an Australian, and several persons born in Europe or Asia. All are now new citizens and new caretakers of the national park system.
