Mapps, Pearson, or Granage Family Genealogist Needed

I am searching for a family genealogist for the Mapps, Pearson or Granage families in York Nebraska.

I live in Palmer Alaska and came into possession of a large archive of letters and photos that belonged to George E. Mapps formerly of York Nebraska. He emigrated from York, probably, to Los Angeles California and finally settled in Alaska, where I assume this archive became availabe when he passed away. Most of the letters in the archive are from folks in York.

It appears the families were farmers prior to the 1950s.

I would love to send this treasure of family communications to a family member of these folks.

Common names in the letters:
Adena M. Grenage, George E. Mapps, N P Pearson, W C Mapps,

Please contact me if you have any Mapps, Pearson or Grenage genealogists in the area.
