The home, which was run by an order of Catholic nuns and closed in 1961, was one of many such institutions that housed tens of thousands of orphans and unmarried pregnant women who were forced to give up their children throughout much of the 20th century.
In 2014, historian Catherine Corless tracked down death certificates for nearly 800 children who died at the home in Tuam between the 1920s and 1961 — but could only find a burial record for one child.
I don’t know how the laws are in different countries but just analysing and matching them against anyone sounds highly illegal to me. Next, people need to first be sequenced. Unless they asked them, how do they have their data if they are highly private.
Maybe my question was misleading: for me it sounded like they only analysed the infant DNA and did not perform matches etc. if they used skull size etc to identify the victims it wasn’t a DNA analysis to identify the victim.
