I was a bus monitor in the early 1990's and we had a child placed at St. Al's as it was known. I beleive it was in Providence or Cranston, RI. Have you tried the catholic church dicese in Providence?
Maybe they can help you! I don't know if St. "Al's" is around anymore but your spelling is correct on it.
Good luck in Finding your family!
Let me know how you make out.
