I received this from Lynn. It's Willis Joshua Milner (not Willis R. Milner). I'm sorry I do not have any available information on the road you are speaking of. It is very possible that there were some Milner's from Lamar/Pike that ended up in Harris County. Even though Willis Milner moved to Greenville, Alabama, some of his sons migrated back to Pike County as adults. I don't have a lot of information on this family other than the earliest family members who are well documented.
