I was on the Marius Black page and it got me thinking, would staunch traditionalist pure-blood families like the Blacks have tolerated raising a Squib child or would they have done something truly horrible like abandon or even go as far as kill it? Marius could have been raised with his family and raised well if they loved him enough to barely tolerate it, but the others would have terrorized him constantly and the parents may risk being disowned/ostracized from society; that is assuming he had a semi-happy childhood. I would not be surprised if he was abandoned and possibly given to someone else to raise.
