I haven't really followed the Hogan family (Bartee is mine), but have looked at it a bit. You are right to caution about the Arkansas Hogan's as being in Joseph's direct line. I looked at that some years ago and if you follow the census records you'll find an obvious problem/conflict with this being his family. The researchers who initially proposed this are also the ones who incorrectly identified Melenah Bartee's maiden name as Anderson (and please OBLITERATE Anderson from any record you might have concerning Melenah). At this point, my money is on Davis Hogan and Catherine.
