Impressed by Jim Bartlett’s prose on various message boards and mailing lists, I asked him to do a guest blog post on using spreadsheets with autosomal DNA results, here it is – Kitty

Using autosomal DNA testing can be a challenge – but it doesn’t have to be. It can be intimidating – but by taking it a step at a time, you can break it down into bite-sized pieces that are much easier. When you decide to use autosomal DNA (atDNA), and to get the most out of it, I recommend three broad areas of focus right from the start:

1. Learn all you can about DNA testing for genealogy and particularly about autosomal DNA (atDNA). The ISOGG wiki is a good place to find good articles, tools, blogs (to keep you up to date), etc. Join email lists and read and ask questions. This is definitely a “continuing education” hobby. We are on a frontier with genetic genealogy – and we are pushing the boundaries every day!
2. Create as robust a Tree as you can – stretch as much as you can to 12 generations, or more. This is the net you need to catch cousins and find your Common Ancestors. This is very important – if you don’t have the ancestors in your Tree, you cannot expect to find a Common Ancestor with a Match.
3. Set up a process for your autosomal DNA project. To determine Common Ancestors you have to share ancestry info with your DNA Matches – you’ll be sending (and receiving) a lot of emails and messages. You’ll want to keep track of what you do; to find info on your Matches; to remember the Common Ancestors you determine; new names, new emails, new links to Trees, etc., etc. You may want to use a spiral notebook as a Diary or Journal of your notes. Some people keep a notecard for each Match, or a folder. I now have over 3,000 matches at FTDNA and 23andMe, so I need something that can handle that many (and more) Matches. Many of us use a spreadsheet – read more to see how to set up one.
