Good luck finding match here

I believe you need a more accurate y test or big y test to get closer to matching paternal link over a thousand years ago, even then it would take some luck. Some say western France northern Spain which historically very feasible even if familytreedna says https://discover.familytreedna.com/y-dna/R-L51/story . 23 info I got and others is from over 6000 years ago and there has been tons of historical movement of ppl since then, so better off tracing chromosomal data and corresponding trees attached.
