Hey Mike,
Technically Jessica is telling you the truth. When we (chinese people) address cousins, we address them as "biao" or "tang" depending on which side of the family (mother or father) and sister or brother... for example...older male cousin would be "biao ge" or "tang ge" and younger female cousin would be "biao mei" or "tang mei". When we address the cousin, especially older ones, as children, we were usually told to call them "name" ge-ge or jie-jie.
Note, amoung the westernized chinese, they really only use the cousin name as reference... unless their family is traditional...
