Stolpersteine in present-day Poland #poland

Gerald and Margaret

I would like to set up " Stolpersteine" to commemorate my paternal grandparents in a small town, then KANTH, SILESIA  now Katy Wroclawskie in Poland. .  This town is  and was near the chief Silesian City BRESLAU/ WROCLAW,  the capital .  

Has anyone the experience of anything helpful , from a Silesian town council?  They have to be approached first , but many state the relevant records were lost after the War.  Any suggestions what to do next.  ?
