CHICAGO — Vernita Gray, a gay rights activist who wed her partner in Illinois’ first same-sex marriage, has died at age 65.

Ms. Gray died late Tuesday of cancer at the same Chicago home where she married Pat- ricia Ewert in late November, family friend Jim Bennett said. Bennett was among friends who were gathered at the home when Ms. Gray died.

Her failing health and her wish to marry persuaded a federal judge to order that an expedited marriage license be granted to the couple ahead of the June 1 effective date of the state’s gay marriage law. A subsequent judge’s ruling then paved the way for more same-sex couples to marry early in some Illinois counties.


Ms. Gray worked for gay rights for decades, advocating for same-sex marriage long before many other activists saw it as a possibility, Bennett said. To win conservatives, she made the case that her Social Security survivor benefits should go to her partner, and her knack for working with people across the political spectrum ‘‘made everyone feel that they had a unique contribution to move us forward,’’ Bennett said.

A former restaurant owner, Ms. Gray worked for the Cook County state’s attorney’s office for 18 years, assisting crime victims and witnesses.

Mayor Rahm Emanuel praised her work for equality and civil rights Wednesday.

‘‘Vernita Gray was an inspiration to all who crossed her path, from President Obama, who knew her by name, to the victims of violence she comforted and the young people for whom she was a fierce advocate,’’ Emanuel said. ‘‘Her legacy can be felt in the many institutions she supported and by every LGBT couple in Illinois who is now free to marry the person they love.’’

Governor Pat Quinn, in a statement, commended Ms. Gray as ‘‘a passionate and driven advocate for equality in Illinois.’’
