Tombstone, Catholic Cemetery of Wijk bij Duurstede
Grave of Johannes Thuis and Gerarda Johanna Thuis-Wesselkamp. I assume Johannes is a son of Wilhelmus Thuis and Hermina Schipper, at least I found a Johannes Thuis, born 28 March 1901 in Didam, son of Wilhelmus and Hermina. A quick search in relevant online indexes did not turn up anything else on this couple.
