Finding Cousins With DNA
Information to Help Identify Connections to Genetic Cousins
Presented below is a chart to help find ancestral ties between Mardon Erbland and people who are predicted by autosomal DNA testing to be his 2nd, 3rd or 4th cousins. The autosomal tests that Mardon has taken are Relative Finder and Family Finder.

The colored columns in this chart highlight the people who would be shared ancestors with Mardon at the following levels: 2nd cousins (yellow column), 3rd cousins (green column) and 4th cousins (blue column).
The green lines identify geographical areas where my corresponding ancestors lived. People who moved from one area to another are shown half in one area and half in another.
What followsis a narrative summary of the information that is shown graphically on the chart:
3rd cousins must share with me a great great grandparent with one of the following surnames: Erbland, Gerber, Messer, Linton, Brown, Meek, Shaffer, Hills, King, Jeffery, Fairman, Terry or Cox plus one unknown surname from the Haut-Rhin portion of Alsace, France. That is, every 3rd cousin of mine must have a great great grandparent who was born with one of these surnames or who has the unknown surname of my patrilineal great grandfather's mother and was born in Haut-Rhin Alsace. Again, if someone is my 3rd cousin but removed by some degree, then that person and I will still share an ancestor with one of these surnames but for one of us that shared ancestor will be one or two generations removed from great great grandparent.
4th cousins must share with me a great great great grandparent with one of the following surnames: Erbland, Gerber, Messer, Linton, Brown, Meek, Welsh, Shaffer, Shearer, Mosher, Baker, Palmer, Hills, Brooks, King, Jeffery, Fairman, Terry, or Cox. In addition to these names, I have 16 great great great grandparents with unknown surnames. Fortunately, it is highly likely that all of these 16 unknown people lived in one of four geographic locations: 1) Kent County England, southwest of Maidstone, 2) Sheffield, England, 3) Haut-Rhin, Alsace, France or 4) Canton Bern, Switzerland.
Cousins who share an ancestor with Mardon Erbland along a female-only line can best be matched using results from mitochondrial testing (mtDNA). Here are the results of Mardon's full sequence mitochondrial test expressed as differences from the revised Cambridge Reference Sequence (rCRS):
These results show that Mardon belongs to mtDNA haplogroup H. Mardon's matrilineal cousins will have a similar set of mtDNA results.
Cousins who share an ancestor with Mardon Erbland along a male-only line can best be matched using results from y-DNA STR and/or y-haplogroup deep-clade SNP testing. Mardon's 67 Marker y-DNA STR results are available on the Results Page at www.Erbland.org. Mardon's y-DNA haplogroup is Q, with the deep-clade SNP results listed here:
P36.2+ L56+, L57+, M346+, L53+, L54+, L55+, L213+, L232+, M3-, M323-, L329+, L330+, L331+, L332+, L333+, L334+
Mardon's patrilineal cousins will have a similar set of y-DNA results.
If you have a genetic match with me as indicated by the results of DNA testing, I would love to explore our connection and try to identify our shared ancestor. Please email me for more details.
