Teen Christian Fiction (1970s?)

I am trying to remember the authors, husband and wife, of a group of books I read in the 1970s, that have to do with a Christian ministry in uptown New York in the 60s and 70s. The books have names of youth on the streets of New York around that time. A couple titles I remember are: Paco. Debs and Dolls. Cindy. Tracy.
Can anyone help me?
