John Steinbeck and his wife Elaine visited Ballykelly on 18th August,1952 to discover where his ancestors had come from and to try and find any surviving members locally. At first they went to the Presbyterian church graveyard where his grandfather had been baptized. Eventually they discovered the Hamilton headstones in Tamlaghtfinlagan Parish Church and one marking Elizabeth (Minnie) Hamilton, who had passed away on February 11th, 1951, aged 84, two years before his visit. Minnie was the daughter of Samuel Hamilton's brother, William John Hamilton and Jane Ritchie. In his article ‘I go back to Ireland’ which was published in 1953 in Colliers Magazine, a photograph shows John Steinbeck crouching beside the two Hamilton headstones.
