Brenda, I looked into the birth register Damme - it belongs to the duchy Oldenburg. There is a Heinrich Nordhoff born on 17 April 1874, emigrated in1881 to America. He had a twin sister, she was named Caroline (Page 13 in org. Church books). Martin Glandorf
By any chance do you have Kampsen ancestors? My wife descends from Johan Bernard Kampsen and Anna Mary Elizabeth Romer. Their daughter Maria Agnes married Bernard Glandorf (b. 1845 in Schwarstopf, Osterkappein, d 1905 Osterfeine, Damme, Oldenburg, Germany).
