According to this record, Star No. 1 was drilled by Hardison & Stewart from July 13, 1884, to March 28, 1885, under lease, presumably from
California Star Oil Co.
On Feb. 1, 1889, CSO bought out Hardison and Stewart's interest in the well and had trouble deepening it in 1895 because it was too crooked.
As a point of reference,
in 1890, Lyman Stewart and Wallace Hardison, along with Thomas Bard, formed the Union Oil Co. in Santa Paula.
Eventually everybody would merge into Chevron CSO's successor Standard Oil Co. in 1977, Union Oil in 2005.
