Escuan, a relevant date seems the most likely option for 6 & 39. I did consider another choice but the date is topical so is the most compelling option.
9 is a composite anagram, though to my mind 'mayor' is doing double duty, which isn't normally allowed. The entry ('this') plus M(a)YOR ('no longer active' accounting for the loss of A) can be jumbled to make TODAYS ROME.
