Walraven van Benthem * appr. 1265, male line descent project. This project is open to any male line decendant and is limited to the specific surname or variants. The main lines from Walraven are well documented. But, there are patches that are unclear. This testing can give us a clearer view of the various branches. With the 37-marker test we will actually be able to narrow down the time frame that the family branched; if necessary we will upgrade to the 67-marker test. Furthermore we will be able to validate existing research and identify others who are related. Familymembers life in The Netherlands, Germany, USA and Canada. Also a member of the Van Grasdorff family joined the project. Van Grasdorff is a possible illigemate branch, descending from Count Baldwin (Boudewijn) von Bentheim.
