Hi Mary, It seems that I heard the name "Crump" mentioned eons ago when I was very young. But I'm not sure. Should there be any possibility of a connection it would have to be by means of a marriage to one of my GG Uncles…Hiram, Horace, Franklin, Charles or Emmett…or my GG Aunts… Martha or Sarah. All Parks. Could, also, be by way of my Great Aunt Josephine; or, Great Uncles… Franklin, Arthur and George…again all Parks. I believe they were involved in the "lumber business" in some way or other all throughout the thumb area…and other parts of MI. Should you believe there's a possibility………get back with me. John E Long
