i ownedmy home in Pa. before my marriage what are my wife's claims to the home

Although the house was pre-marital property, once you added her name, you changed the character to marital property.  That means that your wife has an equitable interest in the property as if she owned it with you all along.  Pennsylvania divides marital property according to equitable distribution, not communitiy property.  What percentage of the marital property (and debt) you each end up with depends on how the court evaluates the factors that are set forth in the statute. There is no presumption that you each receive 50%; it could be more or less depending on the court's analysis.
