ABOUT US
The Miller family’s farming and ranching legacy dates to 1871 when William Richard Broome purchased the Rancho Guadalasca land grant in Ventura County. The “Thornhill” Company is named for William Broome’s son, Thornhill Broome.
After Thornhill Broome’s passing in 1946, the next generation inherited the ranch. Elizabeth Broome Miller, the third generation of the Broome family and her husband, Captain Robert Miller III had four children including Stephen Thornhill Broome Miller, the current CEO & President. Steve’s sons, Marshall and Nicholas, represent the fifth generation of farming.

Over the years, the Miller family has diversified their businesses, while maintaining a core focus on estate vineyard holdings.
“Bien Nacido Vineyard and Duckhorn share their origins from the 1970’s. Both are considered to be among the best at what they do, so it is natural that we source grapes from Bien Nacido for our Migration wines. “
Zach Rasmuson, Duckhorn
“What’s particularly extraordinary is that exquisite quality is achieved across grape varieties and across a broad spectrum of wine styles.”
