Bill de Blasio is my 14th cousin 2x removed. The ancestor who connects us as relative is, Ralph de Neville Sir, of Raby Earl and of Westmorland (1364 – 1425), my 13th grandfather.

Bill de Blasio was born on May 8, 1961 in Manhattan’s Doctors Hospital in New York City. He is the third son of Maria Angela (née de Blasio; 1917–2007) and Warren Wilhelm (1917–1979). De Blasio has two brothers, Steven and Donald, thirteen and eight years his senior, respectively. His mother was of Italian heritage, and his father was of German, English, French, and Scots-Irish ancestry. His paternal grandparents were Donald Wilhelm, of Ohio, and Nina (Warren), who was born in Iowa. His maternal grandfather, Giovanni, was from the city of Sant’Agata de’ Goti, Benevento, and his grandmother, Anna (née Briganti), was from Grassano, Matera. His paternal uncle, Donald George Wilhelm Jr., worked for the Central Intelligence Agency in Iran and secretly wrote Mohammad Reza Pahlavi’s memoir.
