GROOS, GUSTAV (1832–1895). Gustav Groos, businessman and banker, son of Carl (Karl) Wilhelm Apollo and Sophie (Martin) Groos, was born on June 10, 1832, in Strass-Ebersbach, Saxony, the grandson of a Lutheran pastor. He sailed with his father, a forty-nine-year-old widower, three brothers, and four sisters to Galveston on November 20, 1848, on the bark Louis from Antwerp. The family settled at Latium, one of the "Latin Settlementsqv," just east of the line between Fayette and Washington counties in the La Bahía prairie. Many of the new farmers in this settlement, established in the late 1840s, were university graduates and enjoyed a cultural exchange, sometimes in Latin, rare among the pioneers of Texas.
Groos also farmed at Round Top. His father, in a letter dated April 9, 1849, from Friedrich Ernstqv's place near Industry, tells his family in Germany of baking cornbread in saucepans as they "ate little else but bread and meat for three cents per head." The family had just extended a fence for Ernst, who had paid them with two cows and calves, so they were looking forward to fresh milk and summer vegetables. In 1854 Gustav's older brother, Friedrich W. Groosqv, secured a contract to haul supplies to the newly established Fort Duncan in Eagle Pass. Gustav and a third brother, Carl W. A. Groos, joined the business, named F. Groos and Company. The three brothers expanded the firm to include a general-merchandise and banking business. In 1866 they moved the business to San Antonio, where they opened a bank, which later became Groos National Bank.
On December 28, 1865, at Bluff, near La Grange in Fayette County, Groos married Anna Willrich from Uelsen, Hanover, the daughter of Georg Carl and Elise (Kuckuck) Willrich. In 1875 Groos built their home at 231 Washington Street in King William Historic District, San Antonio. It remained the residence of the family until 1979. Gustav Groos died in San Antonio on August 21, 1895; Anna, aged 103, died on November 16, 1946. Both are buried in City Cemetery No. 1.
