One of my sons did this, and he had all sorts of mixed lineage. It did however link him with a cousin of his grandfather, with whom we have made contact.
When you stop and think about it, you guys, like us are imports from generally UK stock, which was mixed with all sorts, like Celtic, Nordic, Iberian, Roman,etc, so given the rate of migration that is occurring at present, it wont be long till the gene pool of humans is totally mixed and there will not be what you could call a "pure breed".
