Bishop Gallagher Society Board member Jack Rajkovich (St. Scholastica '63, Detroit Catholic Central '67) came upon a copy of the 1949 Archdiocese of Detroit's school report at a local antique shop. Jack bought the book and it has now been scanned and can be found by clicking this link, or by locating the icon in the left column of this site.
It is interesting to note the growth in Detroit Catholic school enrollment even before the first of the "Baby Boomer" generation reached school age.
As an example, my parish, Redford Our Lady of Loretto, the boundaries of which takes in parts of Redford and Detroit, had not yet been founded. It's grade school, which enrolled over 1000 students in the late 1960s, is now closed.
A little info on the Detroit Catholic League in 1949. Only 4 sports (with track having been a very recent addition). Not one reference to girls.
