Evans family

Evans is the surname of a muggle family. They must have had some distant magical blood. At least one member, Lily Evans, was a Muggle-born witch. They are related by marriage to the wizarding Potter and Weasley families.

History
The earliest known members of the family were Mr and Mrs Evans, who had two daughters, Petunia and Lily Evans. They lived near Spinner's End in Cokeworth, sharing residence with the Snape family. Lily's parents were Muggles, as was her sister Petunia.

Mr and Mrs Evans were proud of their younger daughter being a witch and appeared to have favoured her over their elder daughter because of it.

They were related to the Dursley family through Petunia's marriage to Vernon Dursley, and the Potter family through Lily's marriage to James Potter.

They were famous for being Harry Potter's maternal family, and were known in the wizarding world for Lily's loving sacrifice that saved Harry from Lord Voldemort when he was just an infant.

This family is extinct in the male line, but not in the female line. When Harry married Ginny Weasley, they became related to the Weasley family through their three children, James Sirius, Albus Severus, and Lily Luna. Petunia's son Dudley Dursley had at least two children as well.

Etymology
Evans is a Welsh or English surname derived from the given name Evan. As a Welsh name, Evan means "young warrior;" it can also be considered a form of the name John, meaning "God is gracious."

Both sisters in the Evans family, Lily and Petunia, are named after flowers.
