CONCORD, N.H. (AP) — Charlie Morgan, a chief warrant officer in the New Hampshire Army National Guard who fought to repeal the federal law that bars her wife from receiving benefits to help care for their daughter, has died. She was 48.

Morgan died Sunday at a hospice in Dover after a battle with breast cancer, said a spokesman for Gov. Maggie Hassan.

Morgan, of New Durham, was a nationally recognized advocate in the effort to repeal the Defense of Marriage Act. She was a plaintiff in a federal lawsuit in 2011 saying the act violated her constitutional rights.

Under the federal act, the Pentagon is required to ignore same-sex marriages, which are legal in several states including New Hampshire. Morgan, after finding out she had cancer, was worried her spouse and their daughter would be unable to receive military, Social Security and other benefits if she died.

"She deserves the same benefits as any other spouse," Morgan said in 2011 at the first-ever national convention of gay military personnel on active duty. "She went through the same stress, fear and concern during my deployment as any other spouse," Morgan said.

Shortly before that, Morgan came out on national television on the day the military's "don't ask, don't tell" policy was repealed.

In February 2012, she visited Capitol Hill to meet with the staff of House Speaker John Boehner to tell her story.

She said her breast cancer was diagnosed in 2008, and she underwent a double mastectomy and chemotherapy. She was declared cancer-free in 2010 and was deployed to Kuwait for one year. She returned home to her wife, Karen, and then-4-year-old daughter. But she also learned that the cancer had returned and was incurable. Continued...
