WEDDING SUNS AND DAUGHTERS (Explanation). The diagram on the previous page gives an overview of the married descendants (sons and daughters) of Pieter Jacobs of Allema and Trijntje Arents (generation II to VIII of the descendants of Jacob Peters from Spijck and Peterke Henrix from Usquert.) As a result, the overview on the page of the married sons is expanded and a new branch is added, namely the descendants of Joannes Willems (of the genus Boelens) and Pieterke Pieters (daughter of Pieter Jacobs and Trijntje Arents). In this new branch, there are relatively many people living in shipbuilding: ship timmerman, shipyard owner and the like. The shipbuilding in the province of Groningen has been an important source of income after agriculture since the 19th century. (b) Wilhelmina Edes Alma (1859-1946). At the top right of the diagram, a married daughter with a surname Alma immediately attracts attention: Wilhelmina Elisabeth Alma, daughter of Edo Wilms Alma (1829-1861) and Margaretha Jans Wieringa (1831-1912). Edo Wilms Alma and Margaretha Jans Wieringa are listed twice in this diagram: in the top in generation VII and about a quarter from the bottem in generation VI. Margaretha is also mentioned in the diagram of the married sons of Otto Rempts, because she marries Johannes ten Oever (1835-1871) after the death of Edo (yellow box at the top). After the death of John, Margaretha marries a third time: to Lambertus Wilhelmus Leber (1845- 1928). The pedigree chart of Lambertus has a big overlap with my own, but Pieter Jacobs van Allema and Trijntje Arents are not in it. Catharina Freerks Alma (1862-1940). Like Wilhelmina Elisabeth Alma, Catharina Freerks Alma is listed on a red background as well (generation VIII). Catharina is a daughter of Frederikus Wilms Alma (1832-1890) and Anna Jans Smit (1834-1877). They are also mentioned as such in generation VI and VII. Wilhelmina and Catharina do not count in generation VIII in the table below. Number of marriages and married children per generation. The following table shows the total number of marriages per generation and the number of children that will marry. The header of the table shows the generation number. In the second row you find letters m and c. These represent respectively the number of couples married in that generation and the total number of children born therefrom. Overall, this table (in the second row) shows that each family has approximately 4 to 5 children on average, but globally speaking, only half of those children get married. Of the 285 children in generation VII, only one-third wil marry. There are indeed a number of adults who do not marry, but most of the unmarried persons have passed away before they reach the marriageable age. The last row of the table shows the number of second and / or third marriages per generation. ARNOLDUS GABRIEL VAN DER DRIFT. With one couple in the latest generation of this overview, I would like to make a separate explanation: ARNOLDUS GABRIEL VAN DER DRIFT (confectioner), born 18 July 1861 in Delft, as son of Arnoldus van der Drift and Maria van Wijk. He marries September 14,  1897 in Appingedam with LEOBINA JOANNA MARIA de HOSSON (31 years). They have three children: Maria Cornelia Elisabeth van der Drift 1898 Johannes Fredericus George van der Drift 1902 Elisabeth Josephina Maria van der Drift 1905. It is nice to mention that Arnoldus is related by marriage to my wife (10 steps) and Leobina in 9 steps to myself. The couple's family card from The Hague shows that the family with three children is enrolled in The Hague on June 10, 1908, coming from Amsterdam, where the children were born. Arnoldus moves again on January 14, 1914, to Brisbane Australia. Leobina moves with the children one week later to Sloten in the province of North-Holland on January 23 . The last column of the family card refers to a bankruptcy and a verdict, without describing the content. I found this couple again in the 'electoral rolls' in Australia in 1919, 1925, 1928, 1929 and 1937 in Lilley, Queensland, Australia (in 1928 and 1929 daughter Elisabeth is mentioned as well). In 1943 Arnold, Elisabeth and Maria appeared on the rolls in Fawkner, Victoria. There I found Elisabeth and Maria again in 1949 and 1954. Finally, I found Elisabeth again on the rolls in Balaclava, Victoria in 1963, 1967 and 1972. So Leobina move first to Sloten and later to Australia. Arnoldus apparently explored it first. ancestry.com.au shows who will be listed in the electoral rolls: Electoral rolls began being compiled for some areas of Australia in the 1840s. At that time only property owners were eligible to vote. In most of the colonies all men were granted voting rights by the 1850s. Half a century later, women were granted voting rights as well. Non-British subjects were not allowed to vote until the 1940s and aborigines until 1949. Therefore, individuals falling into these two categories are not presently included in this database. It is therefore obvious that Arnoldus and his wife and children have adopted the Australian nationality. Leobina died probably between 1937 and 1943, Maria Cornelia between 1954 and 1963 and Elisabeth Josephina after 1972. I have not found any more records of Johannes Fredericus George van der Drift.
