Olive and Ladislav "Ladi" Marmol

Good afternoon, everyone!  I’m hoping someone here can help steer my research in the right direction.  Beginning in the mid-1950s, a woman named “Olive Joyce Marmol” of Southend-on-Sea purchased at least six Tiger Moths (G-ANIX [currently at the Historische Flugzeuge Josef Koch as D-EFTN] as well as G-ANGD, ANTL, ANTT, ANTU, and ANRK) from various civil sources.  I’ve tried to uncover more about Ms. Marmol, but the Internet only produced news of her passing on 1 January 2021, aged 95.

But I learned of an aviator previously unknown to me: Ladislav “Ladi” Marmol, a Czech pilot who by any measure lead an astounding life, much of which was spent establishing glider endurance records in the south of England.  I’m certain the common surname and locations are more than a coincidence!  Apparently, Aeroplane Monthly ran an article about Ladi in April 1998.

Ladi was born in 1920 and Olive in 1926, so my assumption is they were husband and wife.  Does anyone know for certain if they were related, for what venture she was purchasing Tiger Moths (and probably other airplanes), or any morsels that may help?  Thank you in advance!
