How to Trace Maltese Ethnicity Through DNA Testing
Malta sits in the middle of the Mediterranean, which means its population is a genetic amalgamation that doesn't fit neatly into any single European or North African category. If you're Maltese or have Maltese ancestry and want to understand where you come from genetically, the process is straightforward but comes with specific complications you need to account for. The foundational step is submitting a DNA sample to one of the major consumer genetics companies. 23andMe and AncestryDNA are the two most useful options for this particular analysis. Your sample will be processed against reference panels that include Mediterranean populations. The challenge with Maltese DNA is that it straddles multiple reference groups — Southern Italian, Greek, North African Berber, and Near Eastern populations all show up at varying levels depending on which database you use. I ran into a specific issue a few years back when a client with well-documented Maltese family records got wildly different results between AncestryDNA and 23andMe. Ancestry broke his heritage into "Broadly Southern European" with sub-regions pointing toward Sicily and the Ionian coast, while 23andMe's more granular breakdown showed significant North African components that Ancestry was folding into the Southern European cluster. The workaround was running the raw DNA data through a third-party tool like GEDmatch and using their admixture calculators, particularly the Eurogenes K13 and Dodecad K12b models. Those tools handle Mediterranean populations differently and gave a much clearer picture — roughly 60% Southern European, 20% Near Eastern, 15% North African, and a small sub-Saharan component that likely came through historical trade routes.
The reason this matters is that standard ethnicity estimates from major testing companies smooth over the Mediterranean middle ground. Malta was settled by Semitic-speaking farmers around 5900 BCE, later colonized by Phoenicians, Romans, Arabs, Normans, Spanish, French, and the British. Each wave left genetic signals, but the North African and Near Eastern components get classified differently depending on the company's reference panel composition. A company with a stronger Italian reference panel will push more of your DNA toward Southern European. One with stronger North African representation will show higher Maghrebi ancestry. For the most reliable picture, I recommend testing with 23andMe first because their autosomal DNA reference database includes better Mediterranean representation than Ancestry's. Upload your raw data to GEDmatch, run multiple admixture calculators, and compare the results. The MyOrigins 2.0 tool on 23andMe is also worth checking — it sometimes assigns Mediterranean sub-regions that the main ethnicity estimate glosses over. There's a limit to what this can tell you, and it's important to be blunt about that. Consumer DNA tests cannot distinguish between ancient shared ancestry and recent migration in the Mediterranean basin. The genetic overlap between Maltese, Sicilians, and Cypriots is real but the test results can't reliably say whether that shared DNA comes from Roman-era movement, Arab period contact, or something much older. Y-chromosome and mitochondrial DNA haplogroups go further back in time and can sometimes resolve this better. Maltese patrilineal lines frequently show haplogroups J2, E-M78, and G2a, which point to Neolithic Near Eastern and later Mediterranean agriculturalist origins. Maternal lines often carry H, T2, and U5 variants common across Southern Europe and the Near East.
If you have access to relatives' DNA, especially older generations, that helps considerably. Matching with first or second cousins who also have Maltese ancestry lets you triangulate segments and confirm which parts of the genome are genuinely shared across your family line versus appearing by chance. Without that, you're working with probabilities, not certainties. One practical thing to keep in mind: Malta's small population size and historical endogamy mean that many Maltese share measurable DNA with each other beyond what you'd expect from a general European population. If you search for matches and find a high concentration of connections to other people with Maltese surnames — Borg, Ellul, Farrugia, Grech, Mizzi — that's a normal artifact of the demographic situation, not an anomaly in your results.
