"Destined to become HRH Princess Srinagarindra or the Princess Mother, Sangwan was born into a goldsmith family in the Anongkaram Temple community in Thonburi.
When still very young, her father passed away. Under their mother’s care, she and her younger brother were taught to read and write at home.
Sangwan was a precocious reader. Book-rental shops were ideal for those who loved to read. The owner of one local book rental shop liked the bright young girl and waived the rental fees for her. She was able to read as many books as she liked, opening her mind to the vast world of knowledge. She also had the good fortune to attend a temple school for girls, then joined Suksanaree School for Girls, but the family could only afford school fees for one month."
