Overview

Product summary

Review the store description, core capabilities, and common use cases.

Pedigree Thief is a genealogy data gathering tool. The information gathered is intended to be imported into Genealogical DNA Analysis Tool, a program that allows you to manage your DNA matches.

Please note that only English language pages are supported although the extension may function in other language sites.

The extension's primary function is to read pedigree trees ( Geni and MyHeritage) and convert them to Ahnentafel. See also the included Pedigree to GedCom application that can read pedigrees from other sources.

It will also read information on matches from MyHeritage as well as adding a couple of utilities to some GedMatch web pages.

Before using for the first time, right-click the icon and select 'Help' from the menu. This will give guidance to setting up and using the extension. For further help join the Pedigree Thief Facebook group.

Invaluable companion for GDAT. I'm perplexed to see some of the comments in other reviews. I collect DNA data and trees from GEDMatch and MyHeritage on a daily basis. The developer regularly updates the extension to accommodate frequent changes made by these services. It worked great with Ancestry until they threatened all software tools that collect or analyze data from their site with legal action. The facebook support page provides rapid support from many users and from the developer.

Was working great but has stopped reading trees on ancestryDNA (28 Jan 2020). It still says it has access but then when you click there is no activity anymore and it just hangs saying: Pedigree Thief v2.1.5.11 Reading pedigree - please wait

A Must-Have for genealogy, especially those doing DNA match research.

Works great but a few issues. Many Ancestry trees get duplicates in the ahnentafel making that aren't in the original tree leading me to believe that people might be missing or mis-numbered. This leads me to mistrust the data it's giving me. It also crashes sometimes with complex relationships (children of common parents appearing on either side of the tree).

I was hoping this would be a suitable replacement for the no longer working ancestry dna helper. Unfortunately it falls very short. You have to download each matches tree one at a time. Not only that but apparently downloading your matches shared matches only works if you have genome mate pro. I'm not looking to get programs, I just wanted a simple addon like ancestrydnahelper was to simply download my matches data.

This used to work, but doesn't anymore... what has changed? I can't see public trees anymore, it comes up with information from my own family, including my Aunt who is no relation to the person who's tree I was looking into.

Love this app and how it shows the ahnatafel(sp) for pedigrees across all of the dna genealogy matching companies. Great tool! Thanks!

Doesn't seem to be working for me. I get no icon on public member tree pedigrees or on list of DNA matches or on their shared matches. I get a single "Download Ancestors" button when viewing the pedigree of a DNA match. The CSV download works but the file says "Ancestry of null.csv" and shows only name & dates. Was hoping for place too. Help implies something is supposed to happen on a set of matches which is obviously very important with 30,000 matches.

Would be nice if you provided a method to convert the data
