Research has shown that this was George Daglish, born in Brantford, Canada, in 1871, one of twins - the other was his sister Georgina - the children of Joseph Daglish (born England, about 1825, died Brantford, Canada, September 1884) and his wife Sarah Ann Marshall.
The 1920 US Census shows that George Daglish entered the US in 1877 and was naturalised in 1879. He married Allie Fitzgerald (nee Bryan) in November 1896, and they lived in Houston, Texas.
The 1930 US Census shows that George Daglish was President of the company. George died in September 1938 and his wife Allie died in February 1958. I do not believe the couple had any children.
My thanks to Constance Peck for help with details of this family. If anyone has any further information, please let me know.
