DO NOT merge with real people or into the "big tree"

"...Dorea Potter (née Black) (1920 - 1977) was a pure-blood witch, the youngest child of Cygnus Black II and Violetta Bulstrode and sister of Pollux Black, Cassiopeia Black, and Marius Black. She married Charlus Potter and the together had one son. Dorea was the aunt of Alphard, Cygnus and Walburga Black, thus she is the great-aunt of Sirius Black and Regulus Black, as well as Bellatrix Lestrange, Andromeda Tonks and Narcissa Malfoy.[2] As well as this, Dorea is the great-great aunt of Draco Malfoy and Nymphadora Tonks and the great-great-great aunt of Scorpus Malfoy and Teddy Lupin. Dorea and her husband Charlus Potter are possibly the grandparents of Harry Potter since they had one son which would be, most likely, James Potter (Harry's father), since unlike in the muggle world where two people with the same surname can be totally unrelated, Wizards with the same names are usually related in someway or another..."
