Andrychow and Wroclaw

While in Wroclaw, we looked for an old grave. The deceased was born in 1848 in a little town called Andrychow, then in the Austrian Hungarian Empire, but had died in 1898 in the German town Breslau, now the Polish town of Wroclaw.
The cemetery actually had a list of the graves.
We consulted this list before entering the cemetery, but from the list we realized that many graves had no names.

As we walked around the cemetery, we saw that many graves were hard to read because of erosion, but also that many gravestones looked like this:

Possible explanation to be confirmed from some other source:
I once heard that during World War Two the Germans needed metal for their weapons and removed metal signs from cemeteries.
Do you know if this is true?

In any case, we did not find the grave we were looking for.

A few hours later, going by train from Wroclaw to Krakow, we were sitting in the same compartment with a young man around 20 years old, and his mother.
When I asked the young man where he lived in Poland, he first said: It is a small place, you have never heard about it.
I answered: Try me.
He then said he was from Andrychow!

It was strange that Andrychow popped up twice within a few hours.
