First Ascentionists Over Time (Female and Male)

I have always been interested in the history of rock climbing. Lately, I tried to collect data about male and female first ascentionists to visualize climbing progression over tine. However, it turned out difficult to find a lot of data (particularly for female climbers). An exception to the rule is this really nice site http://stara.emontana.cz/climbing-milestones-from-6a-to-9c/  from which I got a lot of information.

It would be great if someone could point me to further sources, and help me correcting the existing data! I find it particularly difficult to get information about, among others,

• first onsights and flashes (who was the first to onsight 8a or flash 8b+?)
• first successful female and male bouldering ascents
• early first female ascents (does anyone know who did the first female 7a?)
• 'first' second ascents (who did the second 8c in the world?)

For routes with disputed gradings, such as Chilam Balam first redpointed by Bernabè Fernandez in 2003, I took the majority grade by all repeaters (9a+/9b in that case).

Graphs below, data (including sources) is available here via Google Spreadsheet or via ClimbStat GitHub (here you can also find the R-code to create the individual graphs. They have been merged together externally to one GIF). Further below you can find an excerpt.
