Cass County records reveal that R. W. Grogan, W. R. Grogan, and T. M. Cochran had a sawmill just across the state line in Miller County, Arkansas, in 1897. The company lumber yard was one mile into Texas on the tracks of the Kansas City Pittsburg & Co Railway Company. A company tram connected the sawmill to the lumber yard.
The obituary for George L. Grogan, in The Gulf Coast Lumberman, noted that his father, R. W. Grogan established the Grogan Lumber County in Cass County in 1890 and the Grogan Manufacturing Company in 1902. The first mill was in Arkansas. A timber deed note of 1902 stated that the Grogan mill in Cass County would be erected and running that year. The Cass County operation was known by the two above names as well as “the Grogan's Sawmill” on the March 1910 edition of the United States Geological Survey map. A company tramway connected the mill with the Texas & Pacific tracks at Bivins. The sawmill was then situated about mile and a half northwest of Bivins.
Grogan Manufacturing appeared in the January 1905 and 1907 editions of the Reference Book of the Lumbermen's Credit Association as a manufacturer of lumber. An article of The Gulf Coast Lumberman, in 1954, reported that the timber supporting the Grogan Manufacturing Company sawmill at Bivins had been cut out by 1908. In June 1908, the Grogans leased the old Bivins Lumber Company place on Mornen survey for loading and tramming and leased (later bought) J. W. Liles property, near Bivins, to build another sawmill. The same article notes that Grogan Manufacturing Company built a larger plant near Linden, in Cass County, in 1908. The Linden plant would continue for many years.
