The meaning of Neff

1. German and Swiss German: relationship name from Middle High German neve ‘nephew’ (later rather broader in application, like cousin in English), hence probably a distinguishing name for a close relation or familiar of a prominent personage. This surname is also found in France (Alsace and Lorraine). In North America, this surname is also an altered form of the variant Naff. 2. Dutch: variant of Neve, cognate with 1 above. 3. Jewish (Ashkenazic): from German Neffe ‘nephew’, cognate with 1 above. 4. Shortened form of Irish McNeff (see McNiff). History: By 1776, several families named Neff had come to PA from Germany. Brothers Francis and Johann Heinrich Neiff (Neff) were Swiss Mennonites who fled first to Alsace and then to Lancaster County, PA, prior to 1715. Both had prominent descendants. Dr. John Henry Neff, a physician, probably a descendant of one of these two, settled in Shenandoah County, VA c.1750. Henry Neff and his wife joined the Conestoga congregation in PA on April 24, 1748. He was minister of Codorus in 1770.

Your paternal lineage may be linked to Niall of the Nine Hostages

The spread of haplogroup R-M269 in northern Ireland and Scotland was likely aided by men like Niall of the Nine Hostages. Perhaps more myth than man, Niall of the Nine Hostages is said to have been a King of Tara in northwestern Ireland in the late 4th century C.E. His name comes from a tale of nine hostages that he held from the regions he ruled over. Though the legendary stories of his life may have been invented hundreds of years after he died, genetic evidence suggests that the Uí Néill dynasty, whose name means "descendants of Niall," did in fact trace back to just one man who bore a branch of haplogroup R-M269.The Uí Néill ruled to various degrees as kings of Ireland from the 7th to the 11th century C.E. In the highly patriarchal society of medieval Ireland, their status allowed them to have outsized numbers of children and spread their paternal lineage each generation. In fact, researchers have estimated that between 2 and 3 million men with roots in north-west Ireland are paternal-line descendants of Niall.

Your maternal lineage may be linked to Marie Antoinette

Because it is so dominant in the general European population, haplogroup H also appears quite frequently in the continent's royal houses. Marie Antoinette, an Austrian Hapsburg who married into the French royal family, inherited the haplogroup from her maternal ancestors. So did Prince Philip, Duke of Edinburgh, whose recorded genealogy traces his female line to Bavaria. Scientists also discovered that famed 16th century astronomer Nicolaus Copernicus traced his maternal lineages to haplogroup H.

What do people with the surname Neff 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.
