Adrianus Roghair, born around the 1600's, is the oldest Roghair found in the family history archive. He married Berendina van Ommeren in 1636. The marriage document is still in existence. The archives of the village of Rhenen only started in the 1620's. The records before that time were either lost of destroyed. The year of birth is only an estimate. The couple had 3 sons: Dirk Ariens, Albert Ariense, and Cornelis Adriannse; but Dirk (the eldest) is the only one on record to have had any children. The 3 sons were mentioned as real estate owners in a nearby village, but no confirmation of this has been made.

Simon Roghair, son of Dirk, had one older brother, Adriaan who developed his own branch of the family. The branch of the family tree consisting of Adriaan will be known as the A Branch. The branch of the family tree that contains Simon is known as the B Branch. Simon married in 1739 to Maria van Daatselaar from Wageningen. They had 7 children. Among these was Johannes.

Johannes Roghair was married in 1783 to Anna Maria Franck of Amsterdam. He was Vicar of the Reformed Church in Bunnik. He served his entire life in the same parish, and a study of his life was some years ago by a professor. Johannes and Anna had 4 children. Among them was Johan Jacob.

Johan Jacob Roghair was a farmer in Barneveld. He married in 1813 to Thérèse Julie van Ravenswaaij of Eperlecque, a city near Normandy and Calais in the northern part of France. His brother was a doctor in medicine. Johan Jacob and Thérèse Julie had 10 children of which 5 went to the United States in 1868. Thérèse Julie died in 1863.

Anna Maria married in 1840 to G. van Ravenswaay. They went to the West Indies where they had 1 child and died.

Joannis was a little boy that only lived 13 weeks and died Dec. 7, 1814 in Veenedaal.

Johannes married in 1846 with Geertruida van Linkenberg of Ede. They had 8 children. He died in Barneveld in 1872.

Thérèse Louise married in 1849 with C. Boshuizen, who died in 1866 in Barneveld. She later married with Gerrit Alberts, who died in North America. She died in 1892 in Barneveld.

Hendrik married in 1854 in Barneveld with Geertje van Veldhuizen of Ede. They went to the United States with Hendrik's sister Thérèse Julie and his brothers Gerrit and Nicolaas. The total group was 21 people. Nicolaas was the head of the family in 1870, because he owned some property in Black Oak, Iowa. He had real estate worth $666(U.S. Dollars) and $344(U.S. Dollars). Hendrik died in Orange City, Iowa in 1878.

Simon was named to his uncle who was a doctor in medicine living in Nieuwer-Amstel. Simon was not married and died around 1888 in Barneveld.

Heimen was married with M. Braak. They had 2 sons and 2 daughters and he immigrated to the United States.

Thérèse Julie married to Boshuizen (the brother-in-law of Thérèse Louise). They had 2 daughters: Thérèse Julie and Elizabeth (both born in Barneveld). Mr. Boshuizen died in 1868 because he was not registered on the immigrating list. Thérèse Julie died in 1917 in the United States.

Gerrit was married in 1860 to Johanna van Zomeren of Barneveld. They had 4 children: Jacoba Gijsbertha, Johan Jacob, Jan and Nicolaas (all born in Barneveld). They went to the United States, and it is told that they had 9 more children. Among them was Louise Anema. Gerrit died in July of 1898.

Nicolaas was married in 1865 with Christina Hendrikse of Ede. In 1866, their son, Johan Jacob, was born. They all immigrated to the United States.

A lot of people moving to the U.S. went to Pella, Iowa, which was founded by Rev. Hendrik Pieter Scholte, one of the "Six fathers of the separation", so it was thought that the Roghairs went there, too.

In 1947, only 17 people in the Netherlands had the name of Roghair. They were all members of the B branch, and are recorded in the genealogy. This is proof that the genealogy is complete, for its Dutch part.

The A branch of the family lost complete contact with the B branch. It is said that Simon and Adriaan did not get along very well. When the A branch thought the name was going to die, around 1906, the two remaining auntles asked the queen if their grandson, born Van Rijn, was allowed to change his name to Roghair-Van Rijn. By royal declaration of 1906, this was approved. The Roghair-Van Rijn family still lives near Barneveld, the place where it all began.

Announcements in newspapers of births and marriages as early as 1818 are still available in the original newspapers.
