In Howl's Moving Castle
, Megan Parry is Howl
's bitter sister. Her children are Neil
. Her husband's name is Gareth. They live in Wales and are Welsh speakers. She has dark hair and eyes and is highly strung by nature with a tendency to subject people - especially Howl but probably also the rest of the family (Neil hints) - to swingeing tirades of complaint and criticism. Howl says she's jealous of him "because she's respectable and I'm not", but she clearly has very prim notions and resents Howl's rather bohemian take on life, finding it humiliating. Megan hints strongly that her husband and Howl get on very badly indeed - presumably he shares her uptight attitude.
