Steven Tyler is of Italian and German descent on his father's side and Polish, English, and Welsh on his mother's.
Steven Tyler was born Steven Victor Tallarico on March 26, 1948, in Manhattan, New York, United States to the family of a classical musician and pianist who taught music at Cardinal Spellman High School Victor Alphonse Tallarico and a secretary Susan Ray Blancha. He has an elder sister named Lynda. The family relocated to Yonkers when he was about nine years old.
Tyler's father was of Italian (from Cotronei, Catanzaro, Calabria) and German (from Berlin and Gerlachsheim) descent, and his maternal grandfather, born Feliks Karol Czarnyszewicz, was a Polish emigrant from Kliczew and Bobrujsk (now, respectively, Klichaw and Babruysk, each of which is in Mahilyow Voblast, Belarus). Tyler's maternal grandmother had English and distant Welsh ancestry; also, on the show Who Do You Think You Are?, his daughter Liv Tyler discovered that Steven's great-great-great-grandfather, Robert J. Elliott, was of half or part African-American ancestry. He was married to Steven's ancestor, Elizabeth "Betsey"/"Betsy" Rollins, in New York.
The son of a music teacher, Tyler started playing drums at a young age, but then focused on singing.
