Tragedy struck four years ago when their daughter Carol died aged 34 of a brain tumour, leaving a husband and two baby daughters.
Christine moved to London to help her son-in-law with the girls. After he re-married last year - to the family's delight - the couple's other children John, 40, and Lynn, 37, encouraged them even more to get out there and enjoy their life.
"When Carol was ill I was going to cancel a planned trip to Africa, but she insisted I go. How unselfish can you get?"
