PCA - fairly conservative denomination. The Presbyterians you mostly hear about are PCUSA, they're liberal. There's the EPC, which I don't know much about. Fairly conservative but I think in theory they ordain women. There's OPC - Orthodox Presbyterians - which are a bit stricter than PCA and the closest thing we have to a sister denomination. And there's the RPC - Reformed Presbyterians - who are a little looser, I think, but still ok.
Oh, and the Cumberland Presbyterians are, I believe, Presbyterian in government only.

Wow, nice summary! I'm cutting and pasting this so I can look some of this up later. I like to be aware of such things. For a high school history assignment I wrote a paper touching on the history of early American Protestantism and its roots in English and Scotch-Irish churches, and I've been interested in the general subject ever since then. Which of the groups you mention are historically most directly related to Colonial-era Presbyterianism?
