We know that Harry, who was an incredible Quidditch Seeker and naturally talented, inherited his skills from his father, who was also a fantastic Quidditch player.
We also know that most of the Weasley children were great at Quidditch as well
- Charlie (I think) was a Seeker on the Gryffindor house team, which we find out in the first book when Harry is chosen to be Seeker
- Fred and George were Beaters for most of their years at Hogwarts
- Ron was Gryffindor Keeper for his last few years at Hogwarts
- Ginny was a Chaser for the Gryffindor team (and Seeker for a bit while Harry couldn't play) and played professional Quidditch as an adult
Five out of seven children being exceptional at Quidditch is too unlikely to happen by chance. As we saw with the Potters, some Quidditch/broom-flying talent can be passed down in the genes. This leads me to my question:
Did Molly or Arthur Weasley ever play Quidditch?
Or, if they didn't, did anyone else in the family play Quidditch that would point to there being stock in the Quidditch genes in the Weasley family line?
I know the Weasley children played Quidditch a lot together in their free time, but the amount of talent they have makes it seem like there must be some genetics involved.
I'm looking for canon-based answers, anything in the books or on Pottermore or from JK Rowling herself.
