Yes I know this family very well, albeit the only one I ever met in person was the one child of John and Frances (as we have it listed), Rolla (or Rollie)Claud, who was may grandfather. He was born in 1884 in Oakland City, Indiana and the family moved to Frisco, Missouri around the turn of the century. There was a Tracer Store in Frisco. Eventually my grandfather and most of the siblings I've heard of (shown below)all moved to Dexter, Missouri. However, there is very few of us left with the last name Tracer in Missouri, none of whom live in Dexter anymore.John's brother married an Ironspiger also and the children of the two families were double cousins. Although I never knew any of my grandfather's siblings, I heard them spoke of many time, Aunt Jo, Aunt Allie, Aunt Nannie, Uncle Jake (he moved to Arkansas and most all of those you listed of his children were raised around Rector and Paragould Ark.), and Uncle Charlie. Some of Uncle Jake's grandson's live in the St. Louis area (Steve and Charlie), although I have never met them. Uncle Charlie and his wife Fanny moved to Oregon, along with most of their children, one's name being Roy.
