Valentine Vollmer Haus – Then & Now
Proudly standing since the 1870s at 501 Florence Street! This classic limestone pioneer home was originally deeded to Louis Huth. He is sometimes referred to as Castroville’s “unsung hero” who led the struggling colony through its earliest, most critical years.
Huth served as Justice of the Peace (elected 1844), Tax Assessor Collector, County Treasurer, County Clerk (1849–58), and Chief Justice (1860–62).
He later sold the property, which was purchased for $200 in 1870 by Valentine Vollmer, who immigrated from Pfalz (Bavarian Palatinate), Germany.
Descendants include Ferdinand Joseph Vollmer (1886–1955, son of Valentine and Mary Wentz), and related family members like Johann Vollmer (1836–1900, buried in St. Louis Cemetery).
Another historic home, the John (Johann) Vollmer Hüs (Valentine’s father), at 615 Lafayette (ca. 1863) highlights the family’s prominence in early building and settlement.
The Vollmer family helped build Castroville’s enduring character through their hard work and resilience as pioneers.
