6/1950 Need help w/ St Vincent's Home for Unwed Mothers in PA

I received a reply to my letter asking for a sacramental document and you guessed it, their records do not go back to the 1920's. According to PA law adoption records may be destroyed after 50 years. They did suggest if my mom was baptized at St Vincents I should contact Rev Olivere in Philadelphia for a Baptismal Certificate. Letter was mailed today. We shall see.
