I have not been able to connect the Kyles or Whitmires to the Van Winkles by any bloodline. Our line (David Lawson VW) came to Hill County, Texas, just before the Civil War. They had left South Carolina,where DL was born, moved to Mississippi, and then went to Texas. Lost track of the Thomas H. Van Winkle bunch, since he apparently meandered to Indiana, where he got married to Elizabeth White Smart, and then they went into Texas. I also looked in our VW genealogy tome compiled by James C. Van Winkle, and those surnames do not appear there. So, they might have been friends/neighbors to your relatives.
