Old Church stained glass window

Well I have had this window since I was 21 Ibought this from a friend who was moving and she did not want to break it in the move and she knew I loved old stuff So he told me she would give me a good deal.I asked her where she got it and she said it was in her family from her father and it was from a church.When she said that I wanted it because it was a religious piece kind of.I have always been attached to things like this all my life.
