Phongpraphai

Princess Phongpraphai was born on 19 December 1867 at the Grand Palace, Bangkok. She was the first child of King Chulalongkorn (Rama V) and Noble Consort Khae Phuengbun. When she was born, her father was still the heir-apparent as Prince Chulalongkorn, Kromma Khun Pinit Prachanart. He became a father at age 14 with Mom Rajawongse Khae who was his nanny. The infant was given a title of Mom Chao in the Serene Highness style. When her father succeeded to the throne in 1868, Mom Chao Phongpraphai was elevated to Phra Ong Chao, or Princess, in the Royal Highness style. Mom Rajawongse Khae, her mother, became the first Chao Chom Manda (Noble Consort) of the reign.

Not long after she was born, the baby was brought by Chao Chom Manda Tieng, the noble consort of King Mongkut (Rama IV) to the king. The king inquired about her parents but the consort instead asked him whom she looked like. He answered that the baby looked like Queen Debsirindra, his queen consort who was Prince Chulalongkorn's mother. He then realized that the baby was Prince Chulalongkorn's. The king was angry with both the Prince and Mom Rajawongse Khae for having a baby at such age, but he did not punish them.

After her father succeeded to the throne, both the princess and her mother had their own residence in the area of Grand Palace. They lived in the Grand Palace all of their lives. She was strict about the old tradition in the Royal Family, although in 1873, King Chulalongkorn cancelled the ancient tradition of have an audience with royalty by standing or sitting on the chair same as the western tradition, instead crouching in the past. Every member of the Royal Family, including the officers do in the new tradition, except the little princess. She still crouched when she was near her father. King Chulalongkorn was so angry with her, he pulled her daughter's tuft for making her standing, but she was still crouching.

While she was living in her residence in the Grand Palace, her father hardly ever visited her. Although he had many children, the King visited his children every spare time, especially Chao Chom Manda Pae Bunnag and her daughter, Princess Srivilailaksana, the Princess of Suphanburi. Caused decreasing importance of the princess, as the eldest daughter, and the eldest child.

She died on 1 March 1942, at the age of 74.
