I believe after 911 the states cut off the flow of information. Back in the early 90's I did a (title search) through the Oregon DMV, you paid $20 and got a shack off paper work and at the bottom was the original owner. After contacting him I received pictures of the car he took in "69" plus the P O P. Unfortunately those days are long gone.
Actually had nothing to do with 911. Federal privacy laws were enacted in the 90's that affected title searches There are usaully ways to get around it, depending on the situations. As with most federal laws that are implemented on the state level, there are wildly differering interpretations and practices from one state to another.
Some states have info going back decades. Oklahoma has info from the 60's, BUT lost data on many cars in 1978 when they changed over to a new computer system. So... it is hit and miss. Unfortunately, mine is a miss. They don't even have a record of me purchasing the car from my brother in 1976. I say they don't have the info. They really do. It just isn't on a computer, so no one will spend the time going through old microfiche to find it. If I KNEW for certain that my car was purchased originally in Oklahoma, I would find someone at the Tax Commission (we don't have a DMV) who would get me access to old records and I would do a search myself. Unfortunately, I have no idea where the car was prior to 1975.
