I am not familiar with this Humphrey. There are some Humphreys (one or more) who are related to the Constant family in Sangamon County. Also Humphreys (various spellings) in MO. related to the Cowhick family I believe, Sullivan and/or Grundy counties. I think there is even a town by that name in one of those counties, but that might be wrong. I do not have my info at hand so this is just from memory. If either of these tie into your research I may have some info for you. Dave H
