 While in 1609 there were still 136 inhabitants in Rehweiler, by 1675 – only 27 years after the Thirty Years' War ended – there were only nine families left, and thus about 50 inhabitants.It was mainly newcomers who settled in the village who strongly boosted the population in the years leading up to 1688, but it shrank again in the wake of French King Louis XIV's wars of conquest.Then came steady growth, even though during the 18th century, nine families emigrated to North America.
