Does anyone know much about Jan Glenrose?

I've come across a brief biography of Fred Culpitt, which mentions he had a partner called Jan Glenrose. As Culpitt was the first magician ever to appear on television it is possible that Jan Glenrose should be recognised as the first assistant (or perhaps first female magician?) to be televised.

I've also read references to a woman of that name being the assistant who played the central role in P. T. Selbit's first presentation of the "Sawing through a woman" illusion (according to Jim Steinmeyer it was Glenrose who took part in the preview staged by Selbit in December 1920 for an invited group of agents and promoters while another assistant, Betty Barker, was sawn in the later public performances)

I'm wondering if this is one and the same woman. Given that Culpitt and Selbit lived at around the same time and both worked for the Maskelyne company at St George's Hall it seems quite possible.

Does no one know anything about a woman with such claims to fame? If so it's kind of sad.
