Hill and her husband Tim McGraw secretly attended the funeral in Florida earlier this month and even insisted on keeping her mother's identity a secret in the obituary.
The passing notes read, "She leaves her daughter Audrey McGRAW and her husband Samuel of Franklin, Tennessee." Audrey is Hill's real first name and Samuel is McGraw's. The couple live in Franklin.
In the 15 years since mother and daughter reunited, Hill discovered she has a half-brother, Zachary, and she was informed that her father, Edwin White, was killed in a car crash when she was about 10.
