Without knowing the details of how that 32% number is calculated, there is no way one can inherit a "percentage" that's not an inverse power of two, like 1/2 (50%) or 1/4 (25%), 1/8 (12.5%), etc.

But if you have ancestors from different generations who married into the Scotch-Irish bloodline, you could get to 32%, undoubtedly by multiple paths.

In other words, it's impossible to get 32% from a single ancestor at any distance of removal.

If, however, the number was 1/32, then it's easy: you are five generations removed from Scotch-Irish ancestor.

There's a big difference between 32% and 1/32, obviously.

Yes, there is. I tested with Ancestry and I am 36% Scandinavian. My grandmother was from Norway. (25%). The rest comes from Scotland and England - those Vikings got around...

Example: If someone is 1/2 of "B has a child with someone who is 1/8 of "B", the child is 5/16 of "B", which is 31% "B".
