Are you overwhelmed with DNA data? Have you ever tried looking at the data in a different way to see what you can learn from it?
The Leeds method of looking at DNA matches is often used for this purpose. Today, I read the blog post, 7-gen-1-sheet, by Ann Raymont. In this post, the author explains how to set up a spreadsheet to display 7 generations of ancestors. Once the spreadsheet is created, color coding can be used to identify patterns such as European roots, lineage society lines or whether a specific source has been used.
Intrigued by how this spreadsheet could be used, I decided to create the page of ancestors. As I was creating the spreadsheet, I decided to use it to look at my ThruLines data. Since I’ve tested myself, my two brothers and my mother, I have four sets of ThruLines. Even though I’ve looked thru this data for each match, I’ve never compared the results.
By adding columns for each of my DNA tests, I was able to record the number of matches for each ancestor from the 4 DNA tests.
Having this data all in one place will help me evaluate my tree in relation to my DNA results. For example, does it indicate an error in my tree if I only have a few matches for that ancestor? Having this data side by side has also allowed me to see that even though I might only have a few matches with descendants of a particular ancestor, my brothers or mother could have quite a few more matches. In those cases, the probability that my tree is accurate increases when I look at all four tests versus looking at just my results.
Now that I have 9 generations of ancestors on my spreadsheet, there are several other ways that I hope to utilize this sheet.
- Color code states of residence in 1850
- Color code ancestors whom I have found an obituary
- Color code ancestors whom I have a Find a Grave source for
- Color code potential DAR ancestor lines
Thank you Ann Raymont for sharing your 7-gen-1-sheet method of looking at our ancestors.
