The day before meeting Chloe, Brenda and Steve Mellon received a recent photograph of their daughter. She appeared tiny in an oversized shirt, but she was smiling, and her Chinese name — Ji Lijun — was written on the photo in black characters. She would soon be Chloe Grace Li Mellon, the first two names for Brenda’s great-grandmother, Chloe Graebe, a strong-willed, good-natured woman; and Steve’s grandmother, Grace McGlothlin, who is 91 and lives in Indiana. Li was kept as a connection to her Chinese heritage.
