The McCain DNA Project is asking all members of the 01 McCain family upgrade their DNA kit to the 111 marker level test. This upgrade will allow a better understanding of the time to the shared common ancestor of the various branches of the McCain family. To date, we know that one or more McCain men left mid Argyll to settle in Taughboyne parish in east Donegal. The exact date of this migration is not known, but we do know that a large group of men did migrate from the area where the McCains were living in Argyll to Taughboyne parish in early Autumn of 1569. There were other groups that followed them in the 1570s until the mid 1590s. The McCain family is appear in paper records in Taughboyne parish in 1630. There was no influx of mid Argyll men from mid 1590s until post 1630, so it appears the McCain family were already living in Taughboyne parish by 1600.
The 111 upgrade will allow us to see if all the McCain branches that have been located descend from the McCain men that have been located in Taughboyne parish in 1630.
