During the Inferno storyline, Elaine and her husband were temporarily transformed into demons by the Goblyn Queen, a clone of their daughter, Jean. 
After the death of her daughter, Sara Grey-Bailey, and possibly her husband Paul, Dr. Grey and his wife Elaine took care of their grandchildren, Gailyn and Joey. 
End of Greys
Elaine was the last member of the Grey family to be killed by the Shi'ar Death Commandos having survived the initial attack. She was protected by both Rachel and Psylocke and watched the deaths of all her family. She denounced Rachel as being her actual granddaughter before dying from an optic blast from Black Cloak that was meant for Rachel.
