She grew up to be a beautiful young woman.
Literal
She [topic-は] grew-up [and-て], beautiful daughter became.
娘 (むすめ) means 'daughter' or 'young woman' — it can refer to one's own daughter or any young woman, depending on context. Here it describes the result of her growth: a beautiful young woman. The comma after 成長して adds a slight narrative pause.
