Since 2011, ARG has extensively researched H.W. Crabb’s To-Kalon estate, including the history of the property’s ownership and use and the surrounding Oakville community. ARG was initially retained to research the history of the residence within the property. ARG determined the house was built in the 1870s by William Baldridge. Baldridge participated in the Bear Flag Revolt and Mexican-American War, which led to the transition of California from Mexico to the United States in the mid-nineteenth century. As a pioneer settler of Oakville, he acquired a land patent from the federal government in 1870 and built a residence within his property shortly thereafter. The Baldridge property was part of To-Kalon estate under Crabb’s ownership for ten years (1889 until Crabb’s death in 1899).

ARG has conducted research at a wide array of repositories and compiled a database of deeds, historic photographs, maps, newspaper articles, and other primary and secondary documents regarding H.W. Crabb’s To-Kalon estate (see Table 1 below)
