I don't think the Catholic Home Bureau was involved in the orphan train phenomenon, but the answer would surely be in its annual reports---a collection is at the New York Public Library in Manhattan :
Catholic Home Bureau, New York. [Annual Report]. New York, 1___-__. __ vols. Catalogued in 1936---and title supplied---by the New York Public Library. The Bureau was established in 1899 and quite active in adoption work in the Archdiocese of New York. (Catholic Home Bureau for Dependent Children, New York)
I know the Bureau did adoptions for the Angel Guardian Home, which was in Brooklyn. There is a capsule case history of an adoptee born 1912 in Brooklyn who was adopted at the Court of Common Pleas of Luzerne County, PA. It appears---without names or exact date of birth---on page 235 of “Adoption Agencies, Orphanages and Maternity Homes : An Historical Directory,” published in 1982. Locust Gap is not in Luzerne County.
