My Meller has a German Y-DNA match

[Peterski]

Sample YF116731 on YFull is my maternal grandfather's brother, Władysław Meller. He is from Wielkopolska region.

Despite having a Slavic haplogroup he now does have a German Y-DNA match with TMRCA around 650 years ago:

So it is possible that some Germanized Slav became a Meller (Germanic surname) and then migrated to Poland.

What does it mean that a sample is "Locked"?

The German match is from Saxony so he might have Sorbian ancestry.

Maybe you should add that it's a subclade of R1a.

Most German emigrants to Poland came from the neighbouring eastern parts of Germany. As a rough orientation Eastern Germans have 30-50% Slavic ancestry autosomally so you can expect roughly something corresponding as for the Y-DNA lineages. So that possibility seems even likely.

To be very correct: Meller will be derived from Möller, hence not be a Germanic (but a German) surname. The German names Möller and Müller are derived from Mühle (a mill) which comes from Latin molina. The etymologically Germanic word for mill is quarn (kvarn), quern (kvern), kürn etc.

Yes it is a subclade of R1a-L1029 and it is for sure a typically Slavic subclade!
