Looking for any information on my great grandfather James Bernard Oldenburg, born October 11, 1874, LaGrande, Oregon, USA. His parents emigrated from Holland to (Alberta?) Canada then returned to Holland. His father was a minister named John/Johann/Jan. Mother's name unknown. James' sister Jenny (married Groot?) settled in Montana. Were there other siblings? James died approximately 1954 in NY city area. Any information would be greatly appreciated!
