The two world wars destroyed many old church records that have been the usual source for family information such as marriages, births, and deaths. By and large, and in so far as my family is concerned, I've not found anything earlier than the 1700s. To be sure, certain families had private records, but finding them now takes small miracles. Most of the Bruning,Brunning & Bruening families seem to have come from the northern part of Germany, - with a few from England. The "-ing" ending still seems more old Norse than Germanic in origin.Keep checking the on-line records of the Mormon Church.
