Some of you may or may not be familiar with Peter Marshall. He was Chaplain of the Senate. He was a wonderful Christian man - born in Scotland, and a Presbyterian. His wife and widow, Catherine Marshall wrote several books, and her most famous was, “Christy,” which was made into a movie and later - a TV series.
