An interesting article on an interesting topic. The very term Galactic Archaeology sounds very intriguing.

THE SUN'S LOST SIBLINGS COULD BE FOUND IN UNPRECEDENTED 'DNA' SURVEY OF 1 MILLION STARS
- This is the first major data release from the Galactic Archaeology survey, known as GALAH, which was launched in 2013 in a bid to provide new insights into the formation and evolution of the Milky Way.
- When complete, the dataset could help astronomers to find our galaxy’s original star clusters— including the one that gave birth to our Sun and its siblings before they were separated. Every star is born in a group, or cluster, of thousands of stars. And every star in the Sun’s birth cluster will have the same chemical composition, meaning that astronomers will be able to trace these lost siblings by analyzing their stellar “DNA”.
