Typed abstract opens with a "Description" of the land and its boundaries, followed by a chronological identification of the grants, deeds, mortgages, and changes in ownership for said property. The earliest portion of the abstract details the grant awarded by Governor Pio Pico, the last Governor of Mexican California, to Jose Ygnacio Berreyesa on 2 May 1846 for "the Rancho Chimiles, containing four square leagues [approximately 17,312 acres] in Napa County." Subsequent pages detail transfer of ownership in 1851 of a portion of the Berreyesa grant to William Gordon (1801-1876) and Nathan Coombs (1826-1877) as identified in the plat, then to others until the 1914 conveyance of a 626.38 acre portion of the Rancho Chimiles to W.H. Lambert. The final page of the abstract is signed by "H.L. Gunn" as President of the Napa County Abstract Company.
