What problem does Preload Number of ThruLines Matches solve?
Preload Number of ThruLines Matches adds a button to the Card view of your AncestryDNA ThruLines. It shows the number of DNA matches and their range of shared cM on every ancestor’s card. The Card view shows no match numbers, so without it you would open each ancestor in turn to find out.
How does Preload Number of ThruLines Matches work?
Ancestry’s pedigree view of ThruLines shows a match count for each ancestor, but the Card view still shows none. In the Card view, a Preload Match Numbers button sits beside Filter. Click it and the numbers load for every ancestor on the page, one card at a time.
Each card gets a badge. A green badge gives the number of matches and the range of their shared cM, from lowest to highest. A red No matches badge marks ancestors with no DNA matches yet. Together, the badges show you the large clusters and the gaps at a glance.

The button counts the cards as it goes, and a large tree takes a few minutes. Click it again to stop; anything already loaded is kept. If Ancestry starts limiting requests, the button says it is waiting and carries on by itself.
The numbers are remembered for each DNA test and reappear when you open the page again. The button then reads Refresh Match Numbers. Click it whenever you want the latest counts, such as after new matches arrive.
