Greetings Everyone & Welcome to the Richardson-2 DNA Project Newsletter
Welcome New Project Members
It is a pleasure to extend a hearty welcome to all our new members: my kinsmen, Jim & Jimmie, Cynthia & Donald, Jason, Ralph, Tom and our continental fellow, Charles Ritcheson. Charles, a retired professor, is a resident of France and our first member with a derivative spelling of the Richardson surname. Again, a most hearty welcome everyone.
Status (See Results Chart)
The are 70 “R” Surname projects. The Rose surname project has 234 members, the Rice surname project has 138 and we rank number 11 out of 70 with 33 members. Of the 33 samples, we’re reporting results for 23. We have 4 kits in process at the lab, 3 upgrades in process and 6 kits to be returned. Four of these were ordered this week so it will be sometime in June before we start receiving results on them.
A HUGE round of applause to everyone for their promotional efforts. Note: Results chart is frequently updated (twice this week) to reflect most recent reported results. Visit at your leisure.
Genealogy & Genetics
Since our last Newsletter, I purchased a good book, DNA for Family Historians by Alan Savin. However, the information I was hoping to find was not covered. So, thought the following Table, shown on the FT- DNA site would be of interest and perhaps answer some questions.

Inheritance Chart

1. The Y-Chromosome test effectively traces the MALE line only. If M0 took this test then it would trace through the left-outermost branch of the chart below.
M0-M1-M2-M4-M8
If a match was found with another male who had been tested then that male is descended from the same male lineage. You cannot tell exactly WHERE the linkage is between the two male researchers, only that they have a common male ancestor SOMEWHERE on their trees on the left-outermost branch continuing back in time.
If a researcher wanted to connect a surname with the surname of M7 one would need to obtain a sample of M7's male descendents i.e. a brother of F3.
Of course if M0 is not interested in genealogy but his sister F0 was, then she could arrange for M0 to take the test (of course she would have to pay!). In this way we can use the Y-Chromosome tests for many of our family lines if we can find living male relatives on the lines we want to test.

2. The mtDNA test on the other hand is tracking DNA that is passed only through the Mother's line and cannot be passed on through the male line.
In this case M0 or his sister F0 can be tested (it makes no difference). However the line tracked now is on the right-outermost branch of the chart.
F0-F1-F3-F7-FF M0-F1-F3-F7-FF
If a match is found in this case between two researchers, then they ARE related, they share a common female ancestor, somewhere.....
For any family branches 'inside' the chart, i.e. not the outermost-male or outermost-female branches then you have to find cousins, uncles, aunts etc. on those lines who would make a Y-chromosome or MtDNA test worthwhile for those branches (i.e. on THEIR chart you are now looking at the outermost branches).
In general it is better for older generations to be tested rather than younger. This is true for several reasons, including: 1. There is less chance of false paternity creating surprises in the data, and 2. If the older relative is the last surviving male in that line then it is a good idea to have them tested while you have the chance..... This is the same as failing to interview a last remaining Uncle while they can still give you vital data.

Well, that is about it for this issue. Have ordered Trace Your Roots with DNA : Using Genetic Tests to Explore Your Family Tree by Megan Smolenyak, Ann Turner. It is my hope that they provide pertinent information to more adequately answer some of your questions.
Hope you’re all having a glorious Spring!
Good Luck With Your Research,
Best regards, DeLores
