The movie is about a young man who start an orphanage. what is the name of the movie?

The closest thing to that category would be Boys Town. the founder was, and I believe this is clearly identified in the film, Father Flanagan, a Catholic Priest. The Padre was originally an Army Chaplain in World War I. Unless I am mistaken, the priestly role was retained in the movie- the lead character was not, say a businessman or banker. A somewhat similar film dealing with a rather rosy picture of Youth-House life bore the very unusual title Johnny Holiday- made in late forties. Lead character was a police sergeant who was a youth counselor at , well, a youth house- played by Wallace Beery, I think.
