Does the PCA Permit Duncanesses?

Our church has been enjoying a terrific Vacation Bible School (thanks to our ladies!).  We have especially enjoyed the musical contributions of Lig Duncan's mom, wife, and the wives of his two brothers.  I have dubbed them the "Duncanesses".  But there is only one question that plagues my mind: Does the PCA allow duncanesses?  Perhaps a study committee can sort this out!
