RESULTS ANALYZED.

Of interest is a number called the MRCA time or the estimated time (in generations) to the occurrence of the Most Recent Common Ancestor between two people. Dr. Bruce Walsh of the University of Arizona has calculated this time to be 42 generations at a 50% confidence when the haplotype (repeat pattern) for two people match each other exactly, i.e. 12 markers out of 12. The haplotype for a person is simply the sequential listing of the recorded "repeats" that have been measured. Dr. Walsh's calculations also show this to be 69 generations at a 90% confidence and 93 generations at a 95% confidence. In most cases, however, the common ancestor will occur much sooner. It does suggest, however, the likelihood you share a recent common ancestor with another person diminishes very rapidly as you match fewer and fewer markers.

• Johann Seitz of Philadelphia line is 12/12  matches and extremely rare, thus the matchups appear to be 100 percent; notice on the 25 marker matchups that 2 cousins whose common ancestor goes back over 200 years have only a differentiation on what's called fast-moving markers. These fast-moving markers, rather than disproving the relationship, serve to show some mutational family line distinctions from common origin. The newest member in this group is located in Adelshofen, Germany, and he, kit 35141 matches on 25 markers with another descendant #5309, thus proving this line's origin in Adelshofen, Ger. These are members of haplogroup 2.

• For Peter Seitz b c 1751-a 2 step mutation is uncommon. Meaning that all the markers in the 12 marker test match between the other testers, in blue, except for 385a, which is 10, 2 off from the 12 in Henry Sides test. Therefore, to test for any possible relationship between Peter and Johann Heinrich Seitz descendants, we would need more distant cousins (ie 6th cousins, for example)  and test for a 1 or 0 step mutation between them (that is, instead of a 10 marker, there would be an 11)  Another useful tool would be to upgrade to 25 markers, but think that will be more useful after some additional Peter Seitz descendants are tested. Member of Haplogroup1

• Michael Sides/Seitz Origins- Walker CoAL, Mecklenburg/Montgomery/Stanly CoNC and MadisonCoMO appear, on 12 markers to be of the same Sides branch, presumed to be Johann Heinrich Seitz m Dorothea Felsinger. Henry Sides and Charles Sides are a 12/12/ match, probable common ancestor.  Henry Sides Jr is said to have a documented line from Johann Heinrich Seitz, however, have not seen any documented proof. Charles b 1818 has not yet had ancestral line determined, although it appears from some estate records that his father may be Daniel Sides b 1794 m Marie C Lefler.  Andrew Sides b c 1740  through Christopher is a 12/12 match (Note that there is as of yet no source documents showing Christopher's father to be Andrew). Peter Seitz b 1755 GER is also a 37 marker match with Andrew Sides of AL>TX of this group (and 25 marker match with the others), showing they have a common ancestor, which would be, at the least, the parent to both. Michael Sides, Jr m Delila Peacock, whose widow went by 1837 to BrownCoIL matches on 25 markers-he appears to be from Michael Sides, Sr, married Mary Magdalena Ludwig's line.  Member of Haplogroup1

• Andrew Sitz results show one mutation, a second ancestor of Andrew Sitz of Lincoln County shows a 24/25 match with the blue Seitz North Carolina group. Member of Haplogroup 1

• The test for Nelson Sides b c 1805, lived Stanly Co, NC shows no relationship yet. Nelson Sides does appear with the other Montgomery CoNC Sides in 1830 and 1840 census, his widow Martha Hatley in 1850 Stanly CoNC. Would like to have more from these lines for comparison, including distant cousins (say, 6th cousins or greater.) Member of Haplogroup1

• Frank Seitz b 1826 > Paducah, KY. No match to other lines, would like to find a match to George & Elizabeth Seitz 

• A descendant of Christian Sides d c 1803 NC through Leonard Sides m Catherine Miller's results are posted. No Haplogroup is suggested. Would like another descendant of Leonard to test, as well as a descendant of Leonard Sides who went to Washington Co, IN.

• One presumed descendant of Johannes Seitz-Philadelphia does not match the other established group; the result so far shows Haplogroup I1b.

• Samuel A Seits does not have a 25/25 match with another line as of yet, but there is a 24/25 match with Jacob Seitz d 1816 NC whose descendants were in Cape Girardeau, MO. These 2 lines match each other and the mutational difference with Jacob may be proving a branch from a common ancestor.

• Valentine Seitz PA> MI is only not a match with the other groups so far but appears to be in a different haplogroup. Need to find some additional descendants of Valentine to test against.

• John C Sides of LA> CO is in Haplogroup I, and does not match other participants at this point. However, the DNA participant says he may likely match the Murphy surname. If so, we will move the results into that group.
