Paul & Pat Blizzard:
They actually had their own ministry as well for several years in the USA, and then they moved to Vietnam and I know Paul is there with his ministry and also is a kind of photographer. He specializes in taking old photos, find their location, and then shooting the new location from the same spot, particularly war photos. He helps orphanages, etc as well. Has a long beard. Absolutely loves the "new" Vietnam. I actually found some news articles on him and his new life over there.
Their daughter (the one that needed the blood transfusion), did unfortunately die around 1989. They had several other children though.
I find it ironic that the Chretians live so near Beth Sarim. (San Diego)
Peter Gregerson died several years ago now.
