I am looking for information about Tyra Wennerström, married name Norgren. She was born on 24 nov 1890 in Sweden. Her grandmothers uncle was quite famous, Victor Kullberg, who fabricated chronometers and had a factory in London. Tyra moved to London probably in the 1920s and married a Swedish businessman in Wood Products, named Norgren. During the war she had a position in the annex of Churchill's 10 Downing St, working as a housekeeper. She died in 1964, probably in december, in Birmingham, Warwickshire. Her Swedish husband probably died before the war, and it is uncertain if she had any children.
