Please understand that this is a collaborative research project

We require the active participation of each member to further this genealogical and genetic study of our surnames and their place in history.

We are testing the Y-chromosome of males with clan surnames to try and reconstruct the male lineages of clan families.

We encourage the use of two types of DNA test for males: STR tests, for example 37 or 111 marker tests and the Big Y-700 test that provides results for both STRs and genetic markers called SNPs.

The latter are extremely important for identifying which branch of the genetic tree a test taker belongs to and establishing the time frame when test takers share a common male ancestor.

All participants will be included in the ongoing studies and by joining the project; you are giving consent for your information to be anonymously included in ongoing genetic genealogy research. 

Your personal identity will not be revealed, but your results will be used to better understand the surnames of Clan MacTavish as a people and the history of our ancestors.
