John Coolidge John Coolidge John Calvin Coolidge III (September 7, 1906 – May 31, 2000) was an American executive, businessman, and entrepreneur with the New York, New Haven and Hartford Railroad, and the first son of President Calvin Coolidge and Grace Coolidge. John Coolidge was born in Northampton, Hampshire County, Massachusetts, on September 7, 1906. He was the elder of the two children of Calvin Coolidge (1872–1933), the 30th President of the United States from 1923 to 1929 and Grace Anna Goodhue (1879–1957), First Lady of the United States from 1923 to 1929. In his autobiography, Calvin Coolidge recorded his impressions of
Anna of Cilli youngest surviving daughter of the late king Casimir III of Poland. It is likely that Anna was born in Celje Castle which was ruled by her father William and his cousin Herman II. William died when Anna was around ten years of age. Two years later, her mother married Ulrich, Duke of Teck, and left Anna in care of Herman II and his wife Anna of Schaunberg in Celje. It is very likely that the girl was illiterate and spoke no Polish. Jogaila's first wife and reigning Queen Jadwiga of Poland, Anna's second cousin, died in July 1399 after childbirth
