Asteroid 236616, Gray, was discovered on May 1, 2006 by Paul A. Wiegert at the Mauna Kea Observatories atop Mauna Kea in Hawaii County, Hawaii. It has a period of 4 years, 107 days.
It was named for Canadian astronomer David Frank Gray (born 1938), a specialist in stellar spectroscopy and a former director of the Elginfield Observatory in London, Ontario, Canada.
The meaning of asteroid Gray seems to be what its name might suggest: "gray" (gray areas, gray-ness, "gray hairs," etc.).
