This is not the Cottrell Y-DNA Project with FTNDA. That project is entirely seperate from this project. Please don't confuse the two different projects.
Cottrell Researcher:
As part of the ongoing research into the Cottrell family name, a DNA study is being carried out to help support current paper genealogies and to help connect with others of the same surname world-wide.
Only DNA from the Y-chromosome will be tested and as such, only males who are directly descended from the Cottrell family name are eligible. This also includes spelling variants of the surname. If you are a female researcher, you can participate indirectly if you have a brother, father, paternal uncle, or male cousin with the Cottrell surname who is willing to submit a DNA sample. Others may also be able to participate by sharing the cost of the Cottrell surname DNA testing. Because we are acting as a Surname Project, we will benefit from a single point of contact with the testing company, be able to easily share results and receive a reduced testing price.
If you want to learn more about Y-chromosomes and genealogy, the testing laboratory has an illustrated tutorial at www.dnaheritage.com, which has been written especially for non-scientists.
The details of the Project can also be found at: www.dnaheritage.com/surnameform.asp?GroupUnique=866516354
The testing laboratory provides a small sampling kit for each participant. This contains two small swabs, which are rubbed on the inside of the cheek and then placed in two vials containing a saline solution. This is quick, easy and totally pain-free and enables the DNA to be safely transported back to the laboratory via the postal service. Each participant receives their own ‘customer code’ and each sample kit is coded so that, by logging onto the secure web-page set up for each Surname Project, participants can check the progress of their sample.
The laboratory will carry out testing on 43 Y-chromosome STR markers*. This is a high-resolution test as it has been found that low-resolution tests (i.e. that use fewer markers) can often only exclude a link between two people. Also, the DNA markers tested are only in the ‘junk’ region of DNA and do not contain medical information. The test will not identify you as an individual as you will likely share the same results with many other individuals. It is therefore necessary to compare your results with others that have the same surname, as the probability of a match of both surname and Y-chromosome results are very low.
When two people with similar surnames match on all 43 markers, a connection to a recent common paternal ancestor can be confirmed. Less exact matches indicate more distant connections or may exclude a connection altogether.
Often, surname studies reveal separate and distinct groups of males, which demonstrate that they do not share the same ancestor. This happens most frequently with variant surnames. Whilst this may be unexpected, this can be extremely helpful (and cost effective) when deciding avenues of further research
.
*None of the markers used by DNA Heritage are ‘in-house’ - all have been published in recent scientific journals.
The price for each 43 marker test through the Cottrell Surname Project study is $199.00.
What happens next?
If you would like to participate in this on-going project, reply to me, the Surname Project Administrator, and I will redirect you to the Cottrell Surname Project ‘join’ page on DNA Heritage’s website. The testing laboratory will then send a testing kit direct to you. You then will need to take samples of your DNA, read and sign the Consent Form, and send the samples back to the testing laboratory. Only when the samples are received will the testing laboratory invoice for the test. The results should be ready within five weeks.
Please feel free to contact me if you have any questions concerning the Cottrell Surname Project. If you would like to help with the project in any way, please let me know.
Yours faithfully,
Richard Cottrell - Surname Project Administrator
