hello. I'm Donna Munger Yates. My father was Donald Eugene Munger, the Donald mentioned who was buried in Wisconsin. His father was Arthur (Arturo) Henry Munger and his father was William Burdette Munger. Joseph Munger was William Burdette Munger's brother. William Burdette has been a mystery. My dad told me he went to William Burdette's funeral in Hayward WI but when I wrote them, they had no record of him. We knew he lived in PA for awhile, but again could locate no records.
I do have a 1928 letter that Joseph wrote to William but it gives no good ancestral information. I have been searching for the names of their parents but haven't had any luck. Maybe this information helps your somehow.
