A 3700-year-old Babylonian clay tablet may be the world’s oldest trigonometric table—and in many ways, more accurate than any today. (The Guardian)

Plimpton 322 was unearthed in the ancient Babylonian city of Larsa, in what is today Iraq.

  • The fascinating new research analyzes Plimpton 322, a 3700-year-old Babylonian clay tablet written in cuneiform. What is cuneiform?
    • Cuneiform is a written language made up of different collections of wedge or triangle shapes. Cuneiform was common throughout many cultures of ancient Mesopotamia, including Sumeria, Akkadia, Assyria, and Babylonia.
      • Mesopotamia is an ancient name for the rich valley of the Tigris-Euphrates river system. The Tigris-Euphrates river system includes most of what is now Iraq, and parts of Kuwait…

New Feature -new filtering system for DNA Matches.

Dear Susi,

We’re excited to announce the release of a new feature — a brand new filtering system for DNA Matches — and we’d be delighted if you would write about it and share with your followers (and of course try it for yourself 🙂 )

Thanks to the growth of our database, most users on MyHeritage now have thousands of DNA Matches. Managing all those DNA Matches, and making sense of them has become a challenge — and this is exactly where the new filtering system comes in!

Filtering lets you view a subset of your DNA Matches at a time, focusing on those that match particular criteria, of more interest to you. We’ve added a beautiful user interface to the DNA Overview page that lets you filter your DNA Matches easily by relationship, by country or by ethnicity. And we’ve added a powerful filter toolbar that lets you do all that, and much more. Using the new filter toolbar, you can combine multiple filters, and filter matches by additional criteria such as those that have a family tree, have shared ancestral surnames with you or have Smart Matches™ with you.

Filtering of DNA Matches can be combined with sorting and searching. For example, you can easily find all your DNA Matches that include “Gordon” in the name of the match or as an ancestral surname, filtering them to view only those who have a particular ethnicity and live in a particular country, while sorting them alphabetically or by the amount of shared DNA.

These powerful capabilities, together with the high accuracy of the matches, make MyHeritage’s DNA Matches the most powerful and easy to use DNA matches on the market today — in our humble opinion 🙂. Anyone who has taken a MyHeritage DNA test or has uploaded DNA data from another service can now take advantage of our new filtering system for DNA Matches, and it’s free! (Some advanced features in the DNA Match review page require a subscription, such as viewing the ethnicity results of a DNA Match).

As part of this update, we’ve also made some improvements to the user interface of the DNA Matches in general. For example, we placed ethnicity and DNA Matches on two adjacent tabs to make it very easy to switch from one to the other for any of the DNA kits you manage.  Viewing family trees of your DNA Matches now uses the Pedigree View.

Many users have told us that we have the best user interface for DNA Matches, and now we’ve made it even better.

Please see the full blog post here with a step-by-step guide on how to use it:

 You can see where family’s met and interlinked.

Today reading the Will, Guardianship papers we learned that Franklin Andrew Pentico became guardian of his Aunt at his  father’s death. His Mother asked the court to appoint him and he had home, job, wife and child and which means she grew up with Aunt Marie, Dad Pentico’s sister. Both born same year.

Follow UP on lost Death Information

Spent some time reading other blogs from family. One listed a news paper clipping in regards to Franklin Marion Hoffman’s death and the date of paper and information on death. So I have a real date. Many of the trees are not accurate alas.

Hoping to locate a D C since I wrote to Wyoming for a certificate they should have on file.

Alas one tree has him dying after I was born.  Not true, Mom could not go to funeral because she was having trouble with my carriage before birth. I was born in July and he was already gone.

Spent some time trying to correct lots of errors in my tree and wonder where all my tree went that was all the way back to Johann Hoffman. Nothing there from Franklin back. Sorta nuts.  I did not remove it, more high jinx by site?

I have lots of newer information to file. Wondering if it should be in blog, on webpage or tree or on paper organized.

Every time a site upgrades something goes away, changes or is very hard to locate. Yet they want it all passworded safe, for what so they can play some more.

As hubby said, children do not start school with pencil and paper they start them with I pad type devices. Then they worry they get overload.

At least of pencil and paper you are responsible for the changes and know what you did with it or should.

Hello, for the next generation of peoples.
