My own family (Roobol) originally is from Rhoon, and I have looked through its sources for quite some years now. Therefore I was quick in getting the information, I knew where to look.
It is difficult researching Catholics in the early 1700’s in the protestant part of the Netherlands. With some of my wife’s lines, Catholics in the province of Groningen and Friesland, we cannot get past 1750.
The Lords of Rhoon never really converted to the protestant faith, as the Prince and the government of the Netherlands wanted. From the reformation up until the late 1600’s, Catholic sermons were held in the chapel of the castle of Rhoon. As with many of these “secret” churches, no administration was kept.
In the province of Drenthe, the first Roman Catholic Church was founded in 1787 in Coevorden, 2 centuries after the reformation. So if your ancestor lived in Uffelte, Drenthe, and was a Catholic, then there wouldn’t be any christening records left.
What one can do in such a situation is:
* Look for a marriage. Catholic marriages had no “legal power” like Dutch reformed marriages had. Therefore, some Catholics, Jews, etc. chose to (also) get married in the Dutch Reformed church. Alternatively, they could have a civil marriage with the schout (sheriff) and schepenen (aldermen).
* Look in tax registers: verpondingen, haardstedengeld, 30e/40e penning, etc.
* Look in judicial registers: maybe they bought or sold real estate, made a will, or a prenuptial contract.
