Hello,
I apologize for writing in English, I'm not from Finland but Czechia.
My objective is to find any man with surname Kopsa who has Y-DNA test or willing to undertake it.
I have found this website https://www.tuomas.salste.net/suku/nimi/kopsa.html
which could indicate that my surname could origin in Finland.
There are 129 men with surname Kopsa in Czechia. The word has no meaning in Czech language.
https://www.kdejsme.cz/prijmeni/Kopsa/hustota/
As of my research, there lived 3 Kopsa men around years 1650 in Czech/Bohemia (dark blue region at map).
My most distant paternal ancestor is Vaclav Kopsa
Václav Kopsa
I have recently confirmed him by Y-DNA test with my distant cousin from US (Vaclav Kopsa is also our MRCA).
Our profiles are at YFull https://yfull.com/tree/E-PH1173/ (kits YF14004, YF72941)
We are in subclade of E-V13, I guess it is not so common in Finland.
Thank you, I appreciate any help!
