Good day and thank you all for the replies as they are greatly appreciated!

I am in agreement with you all and do find the exercise fascinating and challenging. To reconstruct history is always fraught, yet to now add in science on top of (paleo)anthropology might be more so. I will always be a scientist and okay with both change and science's fallibility, but I do not feel science is the be-all-end-all (nothing is). Regretfully as I am more specifically looking into my mother's side, single nucleotide polymorphism results will not be shown as it's for patrilineal lineage. Maybe as the science grows so shall this.

I do feel bad that I may not be able to give my family a more concrete answer yet I will just remind them that this is the nature of these types of investigations. Along that line, I do indeed like the idea of a non-clan, more regional tartan such as for the Angus area and may suggest that to them.

Thank you all. Your experience and kindness have been very welcomed and heartily appreciated!
