Since when was Alice a Prewett?

Family TreeEdit

For those that are wondering how everyone in the Longbottom family is related to each other, here is how i think they are. You can comment on it if you would like to, you can find me here: User talk:Marvel and DC editor

• Harfang Longbottom and Callidora Black could have been Neville's great-grandparents.
• Their children were said to have been a son and a daughter, i think that their son became Neville's grandfather and their daughter was Enid, who was said to be Neville's great-aunt. Enid could have married Algie, who was said to be Neville's great-uncle.
• Harfang and Callidora's son married Augusta and had a son with her named Frank, who married Alice and their son is Neville. Marvel and DC editor 17:54, July 29, 2011 (UTC)

Callidora and Neville are 65 years apart, which is a normal age for a grandmother. Couldn't Augusta have been Harfang's mother? Randomno 17:50, July 29, 2011 (UTC)
