Future Son Chichi
From Dragon Ball Encyclopedia
Where Future Trunks Brief comes from, Future Son Goku had died of his Heart Virus and the world had been dominated by the Future Artificial Humans. She was shown at the age of 43 and still lived in her house in the mountains. Her father still visited her often. She eventually lost her 23-year-old son, Future Son Gohan (her only son in this timeline) to the Future Artificial Humans and was not seen after this.
