Cressida Prewett

Cressida Lilian Prewett (née Smith) (born 1 June, 1960), also known as Cressida, Duchess of Berkshire in the muggle world was an English muggle-born witch and was the daughter of Oscar Smith and Amelia Smith (née Brown). She was born and raised in the countryside of Reading in Berkshire, England. She later turned out to be a witch and so she started attending Hogwarts at age 11. Her childhood best friends include her sister Lilac Smith and her next door neighbours - pure-blood witches Felicity Avery (née Greengrass) and Charlotte Nott (née Greengrass). They would often spend time together.
Cressida attended Hogwarts from 1971 - 1978 and was sorted into Slytherin House, which was uncommon for muggle-borns as Slytherin House usually only accepted pure-blood or half-blood students. She would get tormented and bullied by other Slytherins, but her friends Charlotte and Felicity ensured she had a safe and happy time at Hogwarts. For a muggle-born, she was quite talented with magic. Cressida excelled at Charms and Astronomy. She later studied Arithmancy, which she proved to be talented at as well.
Two years after she graduated Hogwarts, she married pure-blood wizard Lord Rainier Prewett (later Duke of Berkshire) and with him they had three children: Lady Aurora Prewett and twins Lady Anastasia Prewett and Lord Heron Prewett. She also attained the title of 'Lady' after getting married to Rainier and then two years later 'Duchess of Berkshire' after Rainier's father passed away in 1982. She and her husband were named godparents of her friend Charlotte Nott's (née Greengrass) son - Theodore Nott. In January of 1985, she attended her Charlotte's funeral as she died then. 
== Biography ==
=== Early Life (1960s) ===
Cressida Lilian Prewett (née Smith) was born on 1 June, 1960 in Reading, Berkshire, England to muggle farmers Oscar Smith and Amelia Smith (née Brown). As her parents were muggles, she had a normal education for her early childhood. She mostly did farm work after school and helped her parents herd the sheep. Her family wasn't very rich, but they had a lot of land for agriculture and the sheep. Cressida attended muggle school up until age 11 and she learnt to speak mostly French, but picked up a few German words as well. She later learnt more languages from her pure-blood friends Charlotte Nott (née Greengrass) and Felicity Avery (née Greengrass).
Her parents hoped that she would be a kind and caring girl in the future, who would help anyone in need. For most of her childhood she did farm work and would help her parents as much as she could. She would usually spend a lot of time with the sheep after school and read in the fields whilst looking after the sheep. She would also help with the farming as well. Whilst Cressida did pay attention to her schoolwork, she wouldn't focus on it too much, but she still got good grades at school. She was quite smart for her age and she was a charming person as well.
When she was eleven, a member of the Hogwarts staff came to deliver her Hogwarts acceptance letter and explain the news of their daughter being a witch. The next time Felicity and Charlotte came by, she revealed to them she was a witch and to her surprise, Felicity and Charlotte revealed they were witches too. 
==== Friendship (1960s) ====
Except for going to school or going to the market to sell farm goods and sheep, Cressida never really went anywhere else. She was especially close with her sister, as there were only two of them, but they would fight a lot too.
