Table 1 provides a comparison between the Project's participants. Each participant is represented by a Kit Number and a Surname. If the participant wished not to post his surname then the Surname is listed as N/A. Other data associated with each participant includes the Number of Markers, Genetic Distance and 24 GEN. The Number of Markers, NM, refers to the number of markers on the Y-chromosome that were tested in order to make a comparison between two project participants. The Genetic Distance, GD, is the number of genetic differences between two project participants. 24 GEN is the probability that two participants share a common ancestor within 24 Generations as calculated by Family Tree DNA Time Predictor (FTDNATiP). Assuming that each generation is between 20 and 30 years, 24 Generations would cover a period of time going back 480 to 720 years. For example, based upon this assumption, a project participant born in the year 1950 would know the probability of sharing a common ancestor who was born between 1230 A.D. and 1470 A.D. with another project participant. Coincidently the time period between 1230 A.D. and 1470 A.D. roughly approximates the time when surnames began appearing or the time just prior to the appearance of surnames.

The results in Table 1 indicate that the participating members of the project are of 7 distinct families despite the surname similarities. When comparing the genetics between any two members who had at least 25 markers tested the probability of those participants having a common ancestor within the last 24 generations is lower than 4%. Therefore, it is very likely that the surnames of those currently participating in the project originated independently of each other. The common ancestor shared by project participants was someone who lived long before the origins of our surnames.

Although comparing Kit Number N18556 with the other project members yields a higher probability of having a common ancestor within the last 24 generations, this is probably due to low number of markers being used for comparison. If Kit Number N18556 had additional markers for comparison then the percent probability would better reflect the degree to which this participant is related to the other participants.

Table 1: Probability of Project Participants being related within 24 Generations as of 08 October 2007

 

The results presented in Table 1 can be interpreted by using the following statement:

Based upon the analysis of [NM] markers, Kit Number (upper most row) has a genetic distance of [GD] and a [24 GEN] probability of sharing a common ancestor within the last 24 generations with Kit Number (left most column) according to the Family Tree DNA Time Predictor (FTDNATiP).

For example,

Based upon the analysis of 12 markers, Kit Number N18556 has a genetic distance of 6 and a 5.20% probability of sharing a common ancestor within the last 24 generations with Kit Number 40543 according to the Family Tree DNA Time Predictor (FTDNATiP).


Historical Project Affiliations

The table below provides values concerning the affiliation between project participants and their relatives who were enumerated during the particular listed United States Censuses. The values were calculated based upon participant feedback and information obtained from Ancestry.com. It is important to note that surnames listed are how the surname was recorded by the census enumerators. Thus, the surnames may vary from census to census and may not accurately portray the true spelling of the surname. Nonetheless, it portrays the significance of project participation with respect to the number of households having project surnames.

Notes:
No. of hshlds = Number of households present in given Census Year
Part. hshlds = Participating households (Number of households that are represented by a project participant)
Percent Part. = Percentage of participating households based upon the total of households

Interpretation of the table:
There are [no_of_hshlds] households within the US Census that are headed by someone with the surname [surname]. With respect to Y-chromosome DNA results, [part_hshlds] of these [no_of_hshlds] households are related to project participant(s) which accounts for [percent_part] of all US [surname] households enumerated in [census_year].

Interpretation Example:
There are 7 households within the 1810 US Census that are headed by someone with the surname Winegarner. With respect to Y-chromosome DNA results, 3 of these 7 households are related to project participant(s) which accounts for 42.9% of all US Winegarner households enumerated in 1810.
