I spoke with my uncle about Frank.  He had been trying to locate a photo with no success.  He was, however, able to tell me that my grandfather, Sanford Wiseheart, met Frank Springer (his grandfather) when he was about eight years old at their house in Clark County.  Grandpa was born in May of 1923, so that would put the visit circa 1931.  There goes my theory about him having died before the 1930 Census.  That’s alright though.  Maybe I will find him eventually.
