Ethnicity: His father is of Italian descent. And his mother of half Slovak and part Irish.
Boreanaz was born in Buffalo, NY, and moved to Philadelphia, Pennsylvania. When he was seven years old, his family moved to Villanova, PA in 1978, when his father got a job on WPVI, Channel 6. His mother Patti Boreanaz was a travel agent. His father was a weatherman for WPVI in Philadelphia and host of a local kids TV show called "Rocket Ship 7." This early exposure to show business was an influence on Boreanaz, but once he saw Yul Brynner in "The King and I," his acting aspirations were solidified.
