I think people put way to much stock in Carfax and similar, that give you ownership history. The only thing useful in that history IMO is knowing if the car has been a rental - I say steer clear of prior rentals. Other than that, why does it matter who was making the payments prior to you, or how many "whos" there were, or if Horton hears a who?
Maybe the first few owners had financial trouble and had to sell it, or it got repo'd, or they moved out of the country, or had kids and bought a Sienna, or didn't like the gas mileage and bought a Prius, or...
If it's in good shape and you don't get the spidey tingle that there's an issue, just buy the ****ing thing!
