Ancestry DNA Helper

The AncestryDNA Helper has had many failings and issues over the past year.  Support for it by the developer has been minimal.  We recommend you install it in your Chrome extensions for search capabilities at AncestryDNA but to download your files from Ancestry we recommend using the DNAGedcom Client App.

From Jeff Snavely (

The current version of the AncestryDNA Chrome Extension is now available in the Chrome App Store.  It is the currently the same version that I sent out recently, so you don't have to rush to switch over until Chrome releases their update disabling all out of store apps.  When you install the new copy from the App Store, don't forget to disable the old copy or they will both attempt to run at the same time and conflict with each other.

Since the copy from the app store is a new install rather than an update to the existing copy, it will create a new database for that copy.  You will need to either close Chrome and copy your existing database to the new location or, if that seems too complicated, you can do a full scan.  Instructions for copying your database file are below:

Chrome hides it's databases.  The base locations (%USERNAME% is your Windows username) are:

Windows Vista or later:

C:\Users\%USERNAME%\AppData\Local\Google\Chrome\User Data\Default\databases 

Windows XP:

C:\Documents and Settings\%USERNAME%\Application Support\Google\Chrome\Default\databases 

Mac OS X:

~/Library/Application Support/Google/Chrome/



Inside that directory will be a sub-directory for each extension using a SQLite Database.  The format will be "chrome-extension_%ID%_0" where %ID% is the unique id an extension.  To find the ids of the extensions, go to chrome://extensions and check the "Developer mode" checkbox at the top of the screen.  The ids will then appear beside each extension.  With Chrome closed, you will need to go into the sub-directory for the old copy of the extension, copy the file that appears there, then go to the sub-directory for the new copy of the extension and paste the file.  If the filename (a number) in the new copy is different, then you will need to delete that file and rename the file that you just pasted from the old copy to the same name as that other file.  When you restart Chrome, it should now use the existing data instead of an empty file.
