Searching for information on 2005 Hol/Han/QH gelding

I know this is a loooong shot but, I am trying to find out information on a gelding that I own. He was born in 2005 and sold at an auction in Iowa in March or April of 2007. I bought him from the trader that bought him at the auction in Iowa. The only thing the guy knew was that the owner brought him to the auction because she was going through a divorce and had to get rid of him. I’m assuming his information was accurate. This guy bought and sold lots of horses though so it might now be. My horse was buttermilk buckskin when I got him as a 2 yr old but he is greying. I sent his DNA to Texas A&M for genetic testing and it came back Holsteiner/Hanoverian/QH. Does any of this sound familiar to anyone?
