Holding his son Christopher, Josh Dall-Leighton opens the door of his Windham home for Christine Royles and her son Talan on Tuesday, March 24, 2015. Dall-Leighton is planning on donating a kidney to Royles and it was the first time the two had met in person.

Christine Royles posted this message on the back of her car last fall with the hope that someone would see it and donate a kidney to her.

When Ashley Dall-Leighton, left, saw the car window where Christine Royles wrote her kidney donation request, her husband Josh, right, told her to send a text to the number immediately. It turned out that Josh is a strong probable match and plans to donate a kidney to Royles. The transplant surgery will keep him out of work for four to six weeks.
