Hi. I am John Edward Duker, III. My great grandfather was Otto Duker B~1830? He had two brothers Herman and Henry all of them and many of the decedents lived/live in the Baltimore/Annapolis area of Maryland. My aunt Elizabeth has most of the history, which goes back to 1640 in Germany. If anyone is interested let me know and I will make the connection with her - she is in her mid 80's so don't wait to long.
