Grant's son Lester Grove Runyan b. 1887 wife Mae Hoppes; Lester's son Lester Leonard Runyan b.1906 wife Florence Mildred Healy; Lester's son Stephen Michael Runyan b. 1946.
There is a cemetery memorial in Clark County, Ohio that gives John and George Runyan birth and death dates.Peter, Lester G. and Lester L. Runyan are also buried in Clark County Ohio.I have a couple of Bible pages that gives the birth dates of Ullysses Grant, Lester Grove and Lester Leonard Runyan.
