Hi Cal,
Just found a report in the Manchester Guardian of an inquest on Mrs Bertha Landy aged 70, who died on December 13 1934, following an accident at a school concert the day before. The floor of St Clements Church of England School collapsed during a school concert. Her daughter, Mrs Maisie Hagland, gave evidence at the inquest, saying that the room had been far too crowded.
In 1901, there is a Bertha C Landy age 37 in Wavertree with husband William (39), and children Bertha E (17) and Harold J (12), but I can't see them in 1911

PS there were two articles about the inquest; in one of them it says Bertha Landy lived on Upper Parliament St, but doesn't give an address for Maisie
