According to the Hebrew Bible, Dinah (Hebrew: דִּינָה, Modern Dina Tiberian Dînā ; "Judged; vindicated") was the daughter of Jacob, one of the matriarchs of the Israelites, and Leah, his first wife. The episode of her abduction and violation by a Canaanite prince, and the subsequent vengeance of her brothers Simeon and Levi, commonly referred to as "The Rape of Dinah", is told in Genesis 34.

Dinah, the daughter of Leah and Jacob, went out to visit the women of Shechem, where her people had made camp and where her father Jacob had purchased the land where he had pitched his tent. Shechem the son of Hamor, the prince of the land, "seized her and lay with her and humbled her. And his soul was drawn to Dinah ... he loved the maiden and spoke tenderly to her," and Shechem asked his father to obtain Dinah for him, to be his wife.

Hamor came to Jacob and asked for Dinah for his son: "Make marriages with us; give your daughters to us, and take our daughters for yourselves. You shall dwell with us; and the land shall be open to you," and Shechem offered Jacob and his sons any bride-price they named. But "the sons of Jacob answered Shechem and his father Hamor deceitfully, because he had defiled their sister Dinah," saying they would accept the offer if the men of the city agreed to be circumcised.

Jeffrey Charles William Michael "Jeff" Conaway (October 5, 1950 – May 27, 2011) was an American actor best known for his roles in the movie, Grease, and the two US television series, Taxi and Babylon 5. Conaway was also featured in the first and second season of the reality television series, Celebrity Rehab with Dr. Drew. In May 2011, after spending just over two weeks in the hospital, Conaway died at the age of 60 as a result of complications related to pneumonia and the degenerative brain condition known as encephalopathy.

Jeff Conaway was born in the New York City borough of Manhattan. He was raised in the Astoria, Flushing, and Forest Hills neighborhoods in the New York City borough of Queens. His father, Charles, was an actor, producer and publisher. His mother, Helen, an actress who went by the stage name Mary Ann Brooks, taught music at New York City's Brook Conservatory. They divorced when he was 3, and Conaway and his two older sisters lived with his mother. He also spent time living with his grandparents in South Carolina, which gave him enough of a Southern accent that when he accompanied his mother to a casting call for director Arthur Penn's Broadway play All the Way Home, the 10-year-old Conaway landed a featured role as one of four boys. The 1961 Pulitzer Prize-winning play was nominated for a Tony Award for Best Play and ran 333 performances and one preview from November 29, 1960 to September 16, 1961. Conaway remained for the entire run, then toured with the national company of the play Critic's Choice.

Frankie Avalon (born September 18, 1939) is an American actor, singer, playwright, and former teen idol.

By the time he was 12, Avalon was on U.S. television playing his trumpet. As a teenager he played with Bobby Rydell in Rocco and the Saints. In 1959, "Venus" (5 weeks #1) and "Why" went to number one on the Billboard Hot 100. "Why" was the last #1 of the 1950s. Avalon had 31 charted U.S. Billboard singles from 1958 to late 1962, including "Just Ask Your Heart" (U.S. #7), "I'll Wait For You" (U.S. #15), "Bobby Sox to Stockings" (U.S. #8), and "A Boy Without a Girl" (U.S. #10). Most of his hits were written and/or produced by Bob Marcucci, head of Chancellor Records.

Teamed frequently with Annette Funicello, Avalon starred in a number of popular "beach" comedy movies during the 1960s. The wholesome and romantic coupling of "Frankie and Annette" in summer movies such as Beach Party and Beach Blanket Bingo became iconic figures in American films during that era.

Avalon also had straight dramatic parts in the John Wayne historical western film The Alamo, as well as the science-fiction story Voyage to the Bottom of the Sea (1961) with Barbara Eden.
