How interesting! There are some Trenkamps in Iowa. I am looking for any information on the family of August Trenkamp born the 25 of January 1865 reportedly in Damme. He immigrated to the US around 1885. He was married to Maria Agnes Macke Schwabe in 1899 in Adair, Iowa. That sums up what I know of him. Maria "Agnes" was born in Ruschendorf in 1870 to Bernard Heinrich and Maria Anna Baumer Macke.
I would be interested in anything you might know about my August Trenkamp.
Thanks!
