Help fill in the blanks

I've tried to make this database the most complete and accurate site available for information on Indy Car racing.  Unfortunately it can never be 100% complete, too much early data simply no longer exists.  But the goal is to keep updating and trying to make this info as complete as humanly possible.  If you've noticed any mistakes on this site, please feel free to let me know.  With this much data, it's impossible to be 100% mistake free, though I've tried to get as close as possible.  There is also a lot of data missing.  If you have any information that can fill in the blanks I would greatly appreciate it.  Specifically here's what I'm looking for:

Biographical data

Biographical data can be hard enough to come by for some newer drivers, for most older ones it's incredibly difficult.  There are a number of drivers who I don't even have a first name for.  It happens mostly with drivers from 1909 through the early '20s.  If you have any info regarding these areas I would greatly appreciate it:

Statistical data

The biggest holes are with car numbers and chassis/engines, again mostly from the early years.  I'm not sure this data will ever be recovered.  There are also other events that I'm looking for help on, specifically:

There may also be more non points races or drivers entered at races that I know nothing about.  Any information that will help complete the record will be greatly appreciated.
