Your Hansons are difficult to find! According to Union Co Historical Society, there are 5 cemeteries in White Deer Township-Clapp, Highland, Sample(or Semple), Sypher, and Sunrise.
The Highland Cemetery is to the west of Rt 15 and can be seen from highway. Very easy to get to. I have a few relatives buried there. My guess is they are probably there. However, I can't find them in the cemetery list that I have. But, that doesn't mean they are not there. This book contains listings for Union county, but some are only partial listings.
I did find a Dorothy Hanson(1860-1948) buried at Lewisburg Cemetery. If you need directions to the cemeteries, please let me know. I will gladly help.
