Stellar, researchers have already located examples of Jacobi a Tepenecz's signature and they match the writing on Folio 1r. There's one signature that is very embellished and matches less well, but the others are good matches. It's also been established that there was an herbalist/botanist by that name in Rudolph II's court and that the designation "a Tepenecz/de Tepenecz" was awarded by Emperor Rudolph.
Also, I noticed that you sampled two different hands in your "Voynich glyph's [sic]" column. The hand on the final page is not the same as the hand under the zodiac-symbol drawings as you have implied. Plus, these marginalia hands do not appear to match the VMS main text (slant, rhythm, proportion, and pen angle are different). Also, the main text is at least two different scribes and would need to be sampled separately.
