Am I entitled to inherit under intestacy?

Am I entitled to inherit an estate through my biological mother under intestacy? My biological mother's cousin died without a will and my mother is entitled to inherit part of his estate. However, she is deceased as well. I was adopted in 2002 and my biological mother died in 1996. According to N.J.S.A. 9:3-50 "the entry of a judgement of adoption shall: terminate all rights of inheritance of intestacy from or through the parent unless the parent is the spouse of the petitioner or the parent or other relative had died prior to the judgement of adoption." Being that she died years before my adoption, and had no will, am I able to inherit under intestacy through my mother from her deceased cousin?
