Ahrens immigrated from the Kingdom of Hanover to Galveston in 1845, on board the Hamilton. (Chester William Geue and Ethel Hander Geue, A New Land Beckoned, p. 76).
He was situated in Galveston before 1849, when The Galveston Weekly News had printed his advertisement, "Cabinet Making and Repairing. The subscribers furniture manufactory to be found on the corner of Post Office and 22nd Street, directly opposite Mr. Lurcher's Grocery. He is prepared to execute at short notice, all orders for making, repairing, or cleaning any kind of furniture that may be wanted. He keeps on hand a supply of Cedar, Black Walnut, Magnolia, Mahogany, etc. ready seasoned and prepared for use. His prices will be found very low, and the style of work may be seen by giving him a call." In the 1856-7 Galveston Directory, his advertisement was virtually the same but a different address given on Market Street. By 1860, Census data reveals JFW Ahrens is the foremost furniture manufacturer in Galveston County with $1,692 of Total Value of Furniture Produced. The shop employed two hands, to produce 24 desks, 18 bookcases, and 48 tables. Galveston records show that his business continued as late as 1870 (Texas Furniture, The Cabinetmakers and Their Work, 1840-1880, by Lonn Taylor and David B.
