Both Helen Marnie and Lauren Mayberry are from Glasgow, Scotland. Helen is also a fan of Chvrches. She even attended their show at Arches, Glasgow on 2 March 2013.
Later edit: I asked Chvrches on public Q&A session on Facebook if they like Ladytron and the band member Martin Doherty said "Absolutely!".
