Two Brits and Two Canadians in Second Round French Open

It's the usual Russians, Spanish and French players during the yearly French Open, so it's interesting to see that two Brits and two Canadians have made it to the second round.  Elena Baltacha (#83) and Heather Watson (#119) are the Brits while the Canadians are Rebecca Marino (#62) and Aleksandra Wozniak (#162).  Let's see if anyone of them survives and moves on to the 3rd round.
