I am a descendant of Martin Abraham Hiebert (born c. 1840), the child of the third marriage of Abraham Johann Hiebert (1790). I have indirect, but good, evidence that the third wife of Abraham (1790) was Maria Martin Kornelsen (1815), the sister of Eva Kornelsen, who married Johann Hiebert (1816). Abraham Hiebert (1821), the son of Abraham Hiebert (1790), was married to Katherina Enns. Martin Hiebert (c.1840) was a farmer in Neukirch, as was his half-brother Abraham (1821). I would appreciate additional information on the Martin Kornelsen family, as well as any information you may have on the Abraham Hiebert (1821) line.
