Here is how Tuesday's attacks have affected three local families:

        Brian Williams, 29, worked at the World Trade Center on the 104th floor of Building One. When his parents heard the news of the crash they tried to call his apartment. No answer.

        “My sister heard it first on the morning news,” said Peggy Fritz, Mr. Williams's aunt. “We have been waiting ever since.

        “We have heard nothing. We're still just waiting.”

        Mr. Williams, a graduate of Covington Catholic High School and Columbia University, has been working for the Cantor-Fitzgerald brokerage firm since 1994.

        “I don't think anybody in the family is prepared to talk right now,” said his father, Ken Williams, of Edgewood, Ky. “We just want everybody to keep praying for him.”

        Kelly A. Booms, a Cincinnati native who worked for Pricewaterhouse Coopers in Boston, was on American Airlines Flight 11, which was the first to crash into the World Trade Center.

        A relative confirmed that the Miami University graduate was aboard.

        “It's causing people to think how our future is going to be changed, how our lives are going to be different from this point,” said Dr. Jim Kehr, one of Ms. Booms's professors.

        A relative of Doug Cherry, formerly of Terrace Park, confirmed that he was on the 91st floor of one of the World Trade Center buildings.

        “There is nothing positive,” said a man answering the phone, who identified himself as Mr. Cherry's father.
