Your paternal lineage may be linked to Alexander Hamilton
Early in the morning on July 11, 1804, Aaron Burr (then Vice President of the United States) and Alexander Hamilton (founder of the U.S. Treasury) dueled on the New Jersey side of the Hudson River. This marked the culmination of a bitter personal and political rivalry between the two men. Alexander Hamilton died as a result of the duel, but his intellectual legacy survives in the founding documents of the nation he helped build. A piece of his genetic legacy survives as well: in the 21st century, genealogists documented the paternal haplogroups of dozens of Hamilton's living descendants and concluded that the Founding Father's paternal haplogroup was a branch of I-DF29.
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 Ley 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.

The reason is the tendency of people with similar cultural or geographical backgrounds to preferentially mate with one another.
