What causes the SPQR Greeks?

Interesting ideas. The method I used was to 'overlay' the spawn points for these 2 Macedonian / Greek etc generals. IIRC, the 2 spawn points in vanilla are 1 tile North, and also 1 tile North and 1 tile East of Rome itself. Simply relocate Marcus Maxentius (SPQR heir) and Servius Maxentius on the campaign map by changing the appropriate X and Y values after their age in descr_strat. This is what they should look like once you've made the changes:

character    Marcus Maxentius, named character, heir, age 30, , x 95, y 72

character    Servius Maxentius, named character, age 36, , x 96, y 72

You could of course relocate Decius Maxentius (SPQR leader), or Flavius Nepos (diplomat).

This should fix the problem you're encountering, and instead Roman family members should now spawn instead of the Greek ones. I've since relocated Rome, and don't even use the 'overlay' technique, and now all I get is 2 Roman family members, which is good
