View Full Version : Matches at 25 Markers

I feel like a complete ignoramus for asking this question, but here goes:

Is there any relevance at all to a Y-DNA match at 25 markers with a genetic distance of 1? All of my matches share my surname save the one in question. It peaked my interest because my ancestors (1890s) claimed Dutch ancestry, even though our family has only ever used British surnames, and the new match is Dutch. Different sites give me conflicting information, with some stating that a common ancestor within the last 500 years is above 90% likely. Thanks in advance for your collective expertise.
