I'm looking for information on my Brigitta (Grubler or Grübler) Kingsolver, born 1935 in Schlotheim ,Germany. She married Willis Kingsolver and became a naturalized citizen of the US in 1964. I'm looking for her parents' information. I found her obituary, but it only talks about her brothers Harold and Heinrick, and not her parents. Any information would be much appreciated! Thank you!
