INFO-TECH: The Leeds Method May Have Solved a Big Family Puzzle

This method makes cousin connections clearer than black and white.

Earlier this week I gave up hope of meeting one of my 2018 Genealogy Goals because it was too broad and may never happen.

That goal: To find out why my parents share DNA. There's a set of ancestors in my tree that ties my father's and my mother's families together.

But now I have a fighting chance of meeting that goal this year.

A friend pointed me to The Leeds Method created by Dana Leeds. To read all about it:

Here is Dana Leeds' description of her creation, The Leeds Method
Here is her description of using DNA clustering to visualize your DNA matches
Here is her exploration of using The Leeds Method with 4th cousins

I jumped right in and used Dana Leeds' color clustering method with my DNA match list from Ancestry.com. In the first column I added my parents' names with a 0 in front of them. I added my one 1st cousin who took the test, with a 1 in front of his name. And I added 3rd cousins with a 3 and 4th cousins (the first page's worth) with a 4.

The numbers allowed me to sort the names by relationship and then alphabetically. In the end, I used this method on 104 people.

Assigning colors to your DNA matches reveals hidden treasures.

What you'll do is pick one of your matches and see which matches they share with you. In one column, give that person and all their shared matches a unique color. Find the next person in your list without a color and view their shared matches. This time, in a new column, give this person and their shared matches another unique color.

I was seeing a lot of blue (my dad) and green (my mom). But it wasn't until my 10th round of adding colors to shared matches that I saw something amazing.

Three people out of 104 had both green and blue. They were a match to both my mom and my dad.

This is a breakthrough!

Of those 3 people, only 1 has a tree online. I saw lots of familiar last names from my paternal grandfather's hometown. So I wrote to the person who owned the tree. She administers the DNA test for 1 of the 3 important matches.

She told me that the DNA test was for her paternal grandmother, and that I must be a match to her father, too. Yes, I am! Her father is also 1 of the 3 matches. From what she told me, the 2 most important last names tying us together are Zeolla and Pozzuto.

As I explored her tree, I saw that facts weren't sourced, but I have all the vital records from that town on my computer. So I can look up people's birth, marriage and death facts.

After a while, climbing up and across this tree, I found this one couple. Nicolangelo Zeolla and Giovannangela Pozzuto were the parents of someone in this tree. Nicolangelo and Giovannangela are my 4th great grandparents!

The Leeds Method helped me identify a potential shared branch for my parents.

If I hadn't tried plotting the colors as suggested by The Leeds Method, I might never have found the right branch to research.

So where do I take this lead? I'm scouring the town's vital records for births and marriages of children in this family. I'll keep building out the individual families.

I hope I'm going to find a marriage of someone from this gene pool to someone with a last name from my mom's side of the family.

I'm more motivated than ever to find that cousin connection between my parents. And now, it really looks like a goal I can reach.
