Graftombe.nl is a free site for cemetery and graveyard research in the Netherlands and Maasmechelen, Belgium. Graftombe.nl has a goal to make cemetery and related death record research available to genealogists and family history researchers for free.
At Graftombe there are several ways to search for graves and burials.
A simple Surname search.
You can start with a Name Search (Surnames were adopted by law in 1811 so prior to 1811 you may only have a first name, surnames permit wildcards because spellings varied wildly), then specify a Date range, and Region.
You can start with a Region, then select a town, then a cemetery, then a name (left column for region search)
