I'm going by memory here. The original Hal Roach gang got their "Our Gang" name from the title of the first short produced (1922 I think) and the name stuck. Roach sold off his series to MGM about 1938 where it ran until 1944. The name "Little Rascals" came about when the shorts were syndicated for TV in the early 50's. Blake joined the series in 1939 I believe so he didn't appear in the Roach series. The actors you mention above were in the 30's version (the non-silent shorts).To me, Alfalfa, Spanky, Darla and Buckwheat are the "Little Rascals". He joined the cast when most of them were still there.
The actors I saw on TV, though, were mostly from the later years. Blake would still not have been in most of them.I'm going by memory here.

They weren't nearly as popular as the Roach series. The kids from the Roach series were aging, the stories were very thin and the direction wasn't nearly as good. Alas, the novelty had worn off - at least for adults. TV made the series popular once again in the 50's.I don't remember seeing any of the MGM owned Little Rascals shorts until seeing some of them on TCM in recent years.
The names have become interchangeable but there was/is a legal definition.Later on I lived where there was an independent station that had The Little Rascals after school.
