One of the wonderful things about the Dutch records is that women usually retain their surname. This make it much easier to find their children - especially when there may be a number of men with the same name - and also to find their parents.
Levi Cole, born in Michigan, was the son of the immigrant couple Pieter Koole and Thona van Beek. Thona was born 1829 in Zeeland, Netherlands, daughter of Barend van Beek and Neeltje Kramer.
Pieter Koole was the son of Lieven Cole and Adriaantje (Aarjaantje) Leeuw, daughter of Barend Leeuw and Cornelia van Bloois. Aarjaantje was born 24 Jul 1787 in Dreischor, Zeeland, Netherlands.
Lieven Koole's mother was Ariaantje (Adriaantje) Jonker. She was born 3 Nov 1765 in Oosterland, Zeeland, Netherlands, daughter of Lieven Jonker and Jannetje Onderdijk.
The parents of Cornelis were Pieter Mattijsse Koole and Maria Beluijts. She was the daughter of Cornelis Borluijt and Adriaantje Bouman. No exact date of her birth has been found, but she was baptised 19 Oct 1732 in Zonnemaire, Zeeland, Netherlands. Customarily, in this time and place, children were baptised the Sunday following their birth. Which would make Maria born somewhere between Oct 12 and 18.
The next step back in time is Pieter Matthijsse, son of Mattheus and Maria Stoudens. This Maria was born in Dreischor and baptised 25 Oct 1705. Her parents were Joost Stouten and Adriana Cornelisse. The database index gives her the surname Kleijn, but it is not shown on Maria's baptismal record. One more thing to investigate.
This takes us back to Pieter Koole and Lijsbeth Robberegts, the earliest couple identified in this line (so far!). And now I have these surnames to research: van Beek, Leeuw, Jonker, Borluijt, Stoutens, all the spelling variations, and the wives of these fathers!!
