Cholera was often the cause of death. There were several local, regional and national outbreaks in the first half of the 1800's.
See e.g. http://www.vankampentree.com/Html_files/Familytree_omstandig...
for a list.
But famine (hongersnood in Dutch) was also a much seen cause of death: the potato famine of 1845 is a well-known example.
Very often, one does not need an epidemic to explain a series of death. Poverty, and ill health as a result of that, was widely spread in those days.
