This extension downloads list of matching users and ancestor information.
The extension helps with analyzing and comparing your AncestryDNA test results. The automated scanner, accessible using the Full Scan and Resume Scan buttons added to your DNA Home Page, will go through your list of DNA matches and open each one to scan their pedigree charts.
Once the scanning process is complete, you can download your list of matches and pedigree charts as .csv files for analyzing them in a spreadsheet or database program. You can also use the additional search features added to the top of your matches list to search for matches by usernames or exact/similar surnames. The ancestors of matches report also includes an incidence value for each row that calculates how frequently people with the same name and a similar birth year appear among your matches. This value can be useful for detecting possible common lines of descent.
If you have multiple DNA tests under your account, a new shared match icon will appear next to each match allowing your to easily see which other test(s) also match this same result by hovering your mouse over this icon. You can also compare two or three of your tests to each other using the compare features at the bottom of your DNA Home Page.
