Mitochondrial and Y DNA research - New Resource!

-

The three kinds of DNA of use for family history research*


Autosomal DNA

For autosomal DNA (AtDNA), to make best use of your results for research, you will "fish in all the ponds" by testing with Ancestry and 23andme since neither accept uploads, and then upload your raw data to Gedmatch, MyHeritage and FamilyTreeDNA, which do accept uploads - for free! 

The value of autosomal DNA testing is that it covers all of your ancestry back four generations or so, and up to six or seven generations, which is quite long ago. However, as your matches are ever smaller as you go further back in time, your AtDNA will not take you back to your deep ancestry before surnames and record keeping.

Y and Mt DNA

Both Y and Mt DNA will take you back very far, but it may or may not help you find living cousins. So if you can afford only a few tests -- do autosomal for yourself and your oldest relatives. If you can spend a bit more, do a Y test on your father, brother or paternal uncle if possible, because that test will follow your paternal line (your father's father's father, etc.) back thousands of years. And if you can do "Big Y" you can get back to the dawn of humanity. Only men have Y DNA, so women need to test male relatives in the paternal lines.

Mitochondrial DNA

Mitochondrial DNA is the slowest changing and smallest bundle of DNA we have, and we get it from our mothers. Each human gets Mt DNA, but only women pass it along to their children. Since it changes so slowly, test results will rarely find living cousins. However, if you have a mystery line in the past, Mt DNA can confirm or rule out possibilities in that line. Lisa Louise Cooke discusses this in her blog post: https://lisalouisecooke.com/2016/03/21/mtdna-test-dna-for-genealogy/

New Option for Y and Mt DNA

Last year we mourned the disappearance of the FamilyTreeDNA-supported databases for Y and Mt DNA. Truth be told, they were not very useful. Now, we have a new option:

What's the Question?

We genealogists are often told by experienced researchers how important it is to begin with a research question. I resisted doing this for a long time, but now that I use a series of questions to guide my research, the search is more focused and actually finds more of the history of the family I'm investigating. I use a Google Doc as the  research proceeds, where I keep the question(s), the plan, timelines, checklist of resources to search, etc. all in one place. I've seen others use spreadsheets in the same way, perhaps splitting up things in tabs (Excel or Google Sheets). I prefer a document because I add source citations as I find them and I can begin writing up the case right there in the doc as the hypotheses are proven. Specific Questions in Previous Successes As beginners we often have no clue how much and what details we already know about a person, event or relationship, so it's hard to specify what we want to know. But when looking back at successful research, it

Looking for a Needle in a Haystack? GAME CHANGER at FamilySearch

Generated with Bing ImageCreator (AI), March 13, 2024 Where is YOUR Needle, Your Missing Record? Genealogical Proof Standard When we use the GPS (Genealogical Proof Standard) as our guide, we all know that "exhaustive research" can be both tedious and exhausting. Is life long enough to search page by page through all the counties where all the members of a family might have lived, paid taxes, bought, leased or sold property, made a will or died intestate? It is possible that the new Full Text Search at FamilySearch will  eventually  allow us to do just that. It has been estimated that 75% or more of the records at FamilySearch were browsable but not searchable; the only indexes those found in the records themselves. Those records are certainly attainable by using those indexes and browsing to the record of interest, but the process is tedious, often frustrating, and slow. And once found, the record must be read and transcribed to be useful. This new Full Text Search tackles a

Shedding Your Genealogy "Stuff"

AI: Bing Image Creator Generated Changing realities force many of us to consider the future of our genealogical collections. Whether a change in health, a new location or even just downsizing, it can be useful to evaluate what we have now, with an eye to the future. What we can pass along? Plan Ahead First: if you have online trees, create a plan to grant access to interested fellow researchers, even distant cousins. Depending on the website, you may need to add a codicil to your will, or just tell the site whom your successor will be.  Ancestry.com: there are two considerations: your DNA test and your tree(s). It is wise to share your DNA results with a cousin or other relative; no need to wait. Or you can  Assign a Manager .  For overall accounts and trees, there is  Ancestry® Family Plan Memberships .  FamilySearch help file:  How to Connect to a Family Member’s Tree .  B ecause it is a shared tree, a person cannot pass along their FamilySearch account. Ensure that your interested
