This name is exceptionally rare, as you can see on this graph of the "beyond the top 1000" data:
https://www.behindthename.com/top/beyond.php?name=Adner&gender=&type=sample
It was given to only 6 people in the US in 2006 and 2008, and less than 5 every other year. As such I don't think it belongs in the main database.
Can you suggest another?
