She and her husband, Larry, have a 10-year-old daughter and didn't plan on having a second child. Lisa Horchner's heart problem made them especially nervous.

Mark Barnett, 34, of Hagerstown, organized the local link of the national Life Chain by sending letters to about 80 Washington County churches.
He felt compelled to become active in the anti-abortion movement after the birth of his daughter, Courtney, four years ago.
"I realized how precious life was," he said.

She plans to obtain her paralegal certificate by May and study to become a court reporter, she said.
"I'm still very glad that I had my son. My life would be very different, very shallow," she said.
