Your paternal lineage may be linked to men who spread the Semitic languages

Men carrying the J-M267 lineage took part in many waves of migrations over the millennia, and domesticated animals and plants weren't the only things they carried. They may also have been among the communities that spread the Semitic languages, a diverse group that bloomed from a single proto-Semitic tongue in the Levant nearly 5,750 years ago. These men likely carried branches of both haplogroup J and of the Semitic language family through the Arabian Peninsula to the Horn of Africa. Still later, some J-M267-bearing men re-expanded from the Arabian Peninsula back through the Middle East and across North Africa in migrations associated with the emergence and spread of Islam.

Your maternal lineage may be linked to many people of Ashkenazi Jewish descent

A few branches of haplogroup K, such as K1a9, K2a2a, and K1a1b1a, are specific to Jewish populations and especially to Ashkenazi Jews, whose roots lie in central and eastern Europe. These branches of haplogroup K are found at levels of 30% among the Ashkenazim. But they are also found at lower levels in Jewish populations from the Middle East and Africa, and among Sephardic Jews who trace their roots to medieval Spain. That indicates an origin of those K haplogroup branches in the Middle East before 70 AD, when the Roman destruction of Jerusalem scattered the Jewish people around the Mediterranean and beyond.About 1.7 million Ashkenazi Jews living today (nearly 20% of the population) share a single branch of the K haplogroup, K1a1b1a. The diversity of that haplogroup suggests that it arose in the Middle East between 2,000 and 3,000 years ago, and that everyone who shares it today could descend from a woman who lived as recently as 700 years ago. A similar pattern in two other K branches, K1a9 and K2a2, as well as the N1b branch of haplogroup N, has led researchers to conclude that 40% of the Ashkenazim living today – about 3.4 million people – could descend from as few as four women who lived within the last 2,000 years.

What do people with the surname Cohn have in common?

Spoiler alert: it's complicated. People with the same last name are usually no more genetically similar than a randomly sampled group of people from the same population. That said, people with the same surname are more likely to have similar ancestries than randomly sampled individuals. The reason is the tendency of people with similar cultural or geographical backgrounds to preferentially mate with one another. That's why people who share a surname may be more likely to share traits and tendencies in common than people within the general population.
