The 1910 Federal Census confirms that the family was living in Atlanta: Charles, Agnes, Kathleen, Cleeve, but not with grandmother Kelly at the time of the enumeration. Shortly after the enumeration, the family moved on to the next city: June 10th the Atlanta Constitution social page reports, “Mr. and Mrs. Charles Morrison and children and Mrs. Beatrice Stone leave today to make their home in Warren Pa.”
Warren was a lumber town that later turned to oil refining (there are more than one city in the state named Warren, I have not identified which one they moved to. I’m assuming the Warren that is the county seat of Warren County.) Kathleen most likely attended school at St. Joseph School. The school encompassed all of Warren County and children from St. Joseph, Holy Redeemer (Warren), St. Anthony (Sheffield) St. Thomas & St. John (Tidioute) and St. Luke (Youngsville) could attend. "As per parish borders St. Joseph covered most of the north, south and west side of Warren Holy Redeemer covered the east side and was a much smaller parish." (Thanks to Lynnette Hinton, Parish Secretary, for this information.)
The relocation to lasted about a year, and then they were on the move again, this time for Tampa, Florida.
