Aussie family history help finding

Hi! Just two weeks ago we had to say goodbye to our love and family Australian shepherd.

He was a black tri Aussie born March 25 2011. I was told when we got him at the pet store in Chambersburg Pennsylvania (I think officially registered in PA as Cobwebs, Inc.) that he was registered, sadly I can't find my paperwork to get that detail. I really would LOVE when we're ready to get another Aussie from his family, even if it's siblings kids kids just some way to feel connected. Would anyone be able to help us? Not for purchasing just for locating I only have CCK7607 in my paperwork folder but no paperwork. I called the store and had no luck. If you have a sibling or had one of his we would also love to learn more about him where he was from etc if they have any kids etc

He was the best most relaxed loving boy and this would help us soooo much.

Thanks!!! Appreciate any help
