Some of Robert F Jones's ancestry was set out in his 1965 application to become a member of the Sons of the American Revolution (he qualified through his mother’s line). Other information comes from US censuses, marriage and death certificates, newspaper reports and some family trees on Ancestry.
On 6 September 1906 at York, Pa., J Hayden Jones, then thirty-three, married Mary Ida Neeper, aged twenty-three (b 6 Jan 1883 in Harford County, Maryland).
The 1910 census shows the family - John H Jones (36), Mary I Jones (26), Robert F Jones (9) and Sarah I Jones (2) - living on a farm at Coulson Town and Peach Bottom Road, Peach Bottom, with a resident servant John R Sweney (13) who presumably worked on the farm; Hayden was managing a slate quarry. There was a third child, (John) Nelson Jones, born on 22 August 1911.
Hayden, together with his siblings and a bank cashier, was listed as a director of "The Robert L. Jones Slate Manufacturing Company” when its charter was submitted on 25 September 1907. However, the Delta Herald-Times, January 11, 1934, in its 'Twenty-five years ago' section contains the following report from 1909: "John Hayden Jones has entered the employ of the United Peach Bottom Slate Co. as traveling salesman." Whether or not he continued to be actively involved in the family business is not clear. Incidentally, other reports indicate that Hayden and Mary contributed to good causes; for example, Mary helped to raise funds for the war effort during WWI.
Sadly, Hayden became ill and was admitted to the state mental hospital at Harrisburg early in April 1917 where he died on 16 July 1917; he was buried the following day in Delta.
Hayden at least left his young widow a house in Peach Bottom Township, free of a mortgage, and that was where the family was living in the 1920 and 1930 US censuses, with Mary as head, working as a public school teacher; her sister, Oma Neeper, was living with her. Between those censuses the eldest child, Robert, had left home and by 1940 all the children had left home but Oma continued to live with Mary. Mary died on 26 September 1968 at Daytona Beach, Volusia, Florida. She and Hayden are both buried in Slateville Presbyterian Church Cemetery, Delta. (Click here to see a photo of their grave.)
