The Shared CM Project Tool 4.0

Courtesy of Pixabay Mystery Match - What To Do Next You've checked your DNA results, possibly at a new test company, and you find an unfamiliar match sharing a large segment of DNA. While some of the companies assign a relationship, "1C,2R", that may not be accurate due to variables such as "half" siblings or cousins.  There are several tools available to help calculate relationships; one we have seen in presentations and online is the Shared cM Project 4.0 Tool v4.  https://dnapainter.com/tools/sharedcmv4 You can locate yourself in the white square marked "Self" just off the center.  Relationships that share, or are descendants of one or both of your parents are in light or blue gray.  Relationships with which the most recent common ancestor (MRCA) is one or both grandparents are in green, great-grandparents are in orange. The numbers in the squares represent the average shared cMs for that relationship as well as the low and high range.  Notice that ...

MRCA Search Tool on Gedmatch

6 generations of McBees, Willises and Smiths Don't Forget to Check GEDmatch While continuing to build the trees of my McBee DNA matches, I thought about two parts of GEDmatch that allow me to search for my mother's matches, even though she died years before autosomal testing was available. Both of the tools featured here are "Tier 1" tools, which means you need to pay for a month or more to use them.  GEDmatch - Free and Paid My mother's kit, LX517332, is a "Lazarus" kit which I created from the kits of my sister and myself, my father, me mom's brother, and all the cousins I could persuade to upload to GEDmatch. The reason my father's kit is part of the construction is that GEDmatch compares his data to that of my sister and me, and removes our matches to him, which leaves the DNA that we inherited from her. Even after my Tier 1 membership is over, I still have my mom's kit, along with my "super kit" which combines all of my autosom...

How Are You Related? Let Legacy Family Tree Calculate the Ways!

By Marilyn Mullins Schunke Are you related to a direct-line ancestor in more than one way? If you are not certain, do you know how to find out? What method have you used to determine ALL the different ways in which you are related to an ancestor or another individual? This has been my dilemma for years, until I discovered the answer in Legacy Family Tree.  Let me explain. My paternal grandmother, Mabel Clair Maris, was a birth-right Quaker – meaning her parents were both members of the Quaker (Society of Friends) religion when she was born. The Quakers are a very close-knit community and members were “disowned,” i.e. removed from membership if they married outside their faith. The Quakers also tended to move from one community to another as groups of families. Consequently, several of my Quaker immigrant ancestor’s descendants migrated from Pennsylvania to North Carolina and ultimately to Indiana and intermarried along the way. My four paternal 2nd-great-grandparent’s su...
