The obituary I posted for William Dresen said he was born in
"Blehregen, Kreis Bergh. Rgbez. Köln, Preußen"

We have contacted the city hall of Bergheim and spoke with the archive manager. We were told that the correct spelling of the town in question is "Blerichen" -- it is a suburb of Bedburg, in Kreis (county) Bergheim, and is now in the state of Nordrhein Westfalen, Germany.

Blerichen can be found on Google Maps (maps.google.com):
