Fred and his wife emigrated from Prussia to the US in the mid 1850s.
Relative Vernon Paul notes that Fred's son Emil Biesemeyer appears as Emil Biesemer in Kansas, 1885. The surname spelling is similar to Bessemer Bend, Wyoming, and he wonders if there is a connection.
From Wyoming Tails and Trails, www.wyomingtalesandtrails.com/nplatte4.html: Bessemer Bend provided emigrants on the Oregon Trail an easy location to ford the river and thus avoid the tolls on the Mormon Ferry at Casper. In the 1880's and 90's Bessemer had a hotel, the Searight House, and served as the headquarters for the Casper-Rongis Stage Line, owned by William Clark and Son and which provided service from Casper to Lander [Wyoming]. Note: Fred Biesemeyer was a ferryman.
