Family Researchers BEWARE! --New Study Warns
Wonder what the results would have been if it had been conducted on this side of the Atlantic? Perhaps; but personally, I've never found found the horse thief I was promised when I started researching my family four decades ago. However, I have found convicted forgers, murderers, suicides, witches and bastards -- some with official bastardy bonds. I've also found connections to inventors, authors, Presidents and more traditional Royalty. I guess if you dig up enough ancestors, you will get the whole range of characters who make up humankind. For me, that's what keeps me researching. But I guess if one has a carefully constructed conception of one's self, maybe one should tread lightly.

Blog Posts -- The "Underbrush"
Check out the "underbrush" of the blog posts. You can give "click reactions", see how many others have reacted, and view comments. All of these features are at the end of each post. The "click reactions" are "funny","interesting" and "cool". These leave sort of "hash marks" -- actually they increment a counter of similar reactions.

Adding DNA Testing To Your Genealogical Tool Kit—Part 1, y-Chromosome Testing
You have just employed the latest genealogical tool to research your genome to find new branches of your family tree. Your get an impressive looking chart back from the lab that looks suitable for framing but what does it all mean. On the surface it tells you nothing about your family history. Were you under the impression that if you swabbed the inside of you cheek and sent the sample to the lab, they would be able to tell you your entire family history.
DNA is an important new tool for 21st Century genealogists. Someone has said DNA testing has put the "gene: back in genealogy". However, it is a supplement to and not a replacement for traditional family history research.
There are several separate and distinct kinds of DNA research. Some of them are as follows:
1. CSI type identification of a specific individual.
2. Medical testing for specific genes that may have an impact on various health risks.
3. Paternity testing to establish the father and/or mother of a specific individual.
4. Haplotype testing for deep ancestry which may have sociological value in identifying one's ancient clan or tribe.
5. Genealogical testing to establish or eliminate possible family relationships.
It is the latter two types of testing that will be discussed in this series.
Test results for an individual are meaningless for family history purposes when seen in isolation. They take on meaning only when they are compared with databases containing the results of many people. In this case big is definitely better. The larger the database against which you can compare your results, the more likely you will be able learn something useful about your family history.
Genetics is a relatively young field; and it is currently one of the most dynamic areas of scientific research. New discoveries are made constantly. What one thinks one knows today is like to have changed within a few months as more is discovered in the labs.
For the first decade of the 21st Century, the most potent use of DNA in genealogy research has been for y-chromosome comparisons. Only males have y-chromosomes. Therefore, only males can be tested for y-chromosome DNA. Men pass a copy of their y-chromosome genes to each of their male offspring. In a vast majority of these intergenerational transfers, the markers on the y-chromosome genes are copies exactly. This allows researchers to follow lines of ascent backward in time. However, in a very small percentage of transmissions, mistake or mutation is made in the marker copying process. This small number of mutations is what allows us to differentiate between different family lines. While y-chromosome results are useful, the test results only apply to a small part of a male's family tree.
In the following illustration, note that the y-chromosome test result only give information about one of the eight great-grandparents. This decreases with each preceding generation to one of sixteen great great-grandparents and one of thirty-two great-great-great-grandparents, etc.

Southern California Jamboree Coming in June
Unfortunately, I'll miss Jamboree 2010. I'll be in Nashville, TN that weekend for the Bris of a new grandson. Sometimes that end of the family tree takes priority! However, I hope some of you can attend at least one day or more.
