Cucamonga, Rains House

John & Merced Rains, as the owners of Rancho Cucamonga, built this home in 1860. He was a former Texas Ranger, she the daughter of Isaac Williams and sister of Francisca Williams Carlisle McDougal Jesurun. Merced and Francisca inherited Rancho Chino, then Francisca and Robert Carlisle bought out Merced and she and John bought Cucamonga. Oh, it gets even more interesting. Did Robert murder John? Did Robert attempt to murder Merced? We'll never know.
