Hello Gail, Could not find anything re an Allenberg cemetery in or around Milwaukee area. However, I have come up with a strange coincidence.....I found a Nellie Rehling, died 05 Jan 1969 buried in St Adalbert Cemetery. Maybe it's a long shot but if the name of the cemetery was passed along verbally, I can see how it could have been mis-pronounced or heard wrong?? Any how, if you want to take a look at the listings, go to www.cemeteries.org That is the Archdiocese of Milwaukee cemetery site. Click the genealogy link at the top of the page & then put in just the surname & it gives you all the listings for all the cemeteries in their system. If you have trouble with it, give me a holler & perhaps I can help.
