Re: Interpretation of an eventual jewish background from a dna test #dna #hungary

Regarding your question about a y-DNA test: the person you think has Jewish ancestry is connected to you through your paternal grandmother. The y-chromosome is only found in men and thus is passed down from your paternal line only - your father, his father, and so on. So since the great-grandfather you think is Jewish is (maybe) connected to you through a female ancestor, a y-DNA test won't tell you anything useful about him. It will only give you information about your paternal grandfather's father - the non-Jewish one from north Germany.

As for your question about whether MyHeritageDNA's ethnicity analysis confirms that your grandmother's father was Jewish: in my opinion, it is hard to treat your test result as probative because MyHeritageDNA is, at best, notoriously imprecise with its ethnicity estimates. See here for a post in this forum which discusses some of its problems:

If it is available in your country, I might consider testing on AncestryDNA. If it comes back with a result that you are ~9-15% Jewish, that could be a useful clue, although ideally you would also be able to find probable cousins in your DNA matches who have traceable Jewish ancestors who came from the Novi Sad area. That might help point you in the direction you need to locate documents proving the connection between your possible great-grandfather Ignatz Almuslin and your DNA matches' ancestors.
