My father immigrated to the U.S. in 1950. The names above are his parents and that is the only info I have on them. Their first son, also Richard (born 1912, died 1974) married Helen and they had no children. My father was born in or near Amsterdam, The Netherlands. My grandparents graves have been dug up since after my uncle's death, my father was not made aware that up-keep payments had to be made. My father's birthdate is Feb. 23 1920, died June 21, 2002 (Cleveland). I appreciate anything you can tell me. Pat D.
