Am looking for German information on Henry C. Thielker (1862) and Frederick E Thielker (1859). They were born in Westphalen to Anna Marie Dubbel and Frederick Thielker. The boys immigrated to the United States in 1881, owning a carpentry business (Thielker Brothers) together in St Louis most of their life. I can't find any German record of them or their parents, I also can't find any immigration record for them.
Any help would be greatly appreciated!
