Just ran across your message here. Charles von Berg was my adoptive grandfather, Jack C. Von Berg was my father. As you know, Martha Louise Mayes, was the adoptive mother to Jack and his birth aunt. Would be interested in seeing some of the original photos of von Berg and if you want to share any of the info I would be delighted. Charles VB died in 1918 when Jack was 8. The house burned down and everything destroyed except for what is in the UA museum and a couple of photos given to me as I was growing up. Would like to hear from you.
