What were the names of Robert E. Lee's siblings?

Question:

What were the names of Robert E. Lee's siblings?

I'm trying to trace my family tree and know that my great grandmother was the last named lee on our side. So, most of her grand and great grand children were all given the middle name of Lee in rememberance of the historic family. No one seems to recall though whether she was a directly down from Gen. Lee or one of his siblings. Besides paying for a geneology tree, does anyone happen to know the names of General Lee's siblings and their children? There's got to be a die hard history buff out there somewhere!
