Hey guys, I was just doing some research for my first fic (about Grindelwald) and have a couple issues:

Does anyone have any ideas as to Grindelwald's birth-year? I know he was a few years younger than Dumbledore, who was supposedly born in 1881? (Is that true?)

Also, does anyone remember when exactly he was killed in book 7?

Kind of unrelated, but is there any given information as to which grandparent (maternal/paternal) of Victor Krum's was killed by Grindelwald?

Thanks in advance! I am really excited about writing my first story. :-)
