A perfect bone marrow match was never found for young stage actress Shannon Tavarez, who died of leukemia in November, but her family and supporters have vowed to work tirelessly to save others. A bone marrow donor registry drive has been organized in memory of the 11-year-old 'Lion King' star.

Those wishing to donate can head to DKMS, a bone marrow transplant center, located in Harlem, N.Y., on Sunday to get tested. (The test is a simple inner cheek swab.) Tavarez's mother, Odiney Brown, told the New York Post that helping others in need of a bone marrow transplant was one of Shannon's main goals.

The actress played Young Nala from September 2009 until last April, when she began feeling pain in her lower back and legs. Soon, the emerging star was diagnosed, and the search for a donor began.
