I grew up in the small town of Riverton, NJ, right across the Delaware river from Philadelphia.  A creek that fed into the river had white clay deposits, and I heard tell that a few local people in the 1960s would gather and use it.  There were only a few pockets here and there in the 1990s when I started learning ceramics, but when the water washed away the dirt, new pockets would be exposed.  Unfortunately, I didn't know enough about testing to do anything with it, but I've always wondered if it was a kind of kaolin ball clay.  I know that defies logic, but ball clay is basically secondary clay, and kaolin comes from feldspar that has broken down. Today, I live along the kaolin belt in Georgia, and there's lots of exposed kaolin that gets water washed. This NJ clay was fairly plastic. I once found an article about porcelain clay from northern NJ, but it didn't explain much.  I saw this article about the porcelain when it came out and immediately wondered if this porcelain was the same type that I found.  Next time I go back, I'm going to look, and if I find any, I'm going to test the living daylights out of it!
