I'm going to make the whole Finnish Quidditch world championship team. This is the captain of the team, Niilo Lahti. He is the keeper. The broom was the most difficult part of the pic, as we don't have a proper broomstick in HM (yet), or at least I don't remember seeing one.
for your family picture I would guess either the center man, He just strikes me as a older gentleman.
or the Women on the far right, her pose is more maternal and her son (i think thats her son) is bigger then the rest.
But as a stab in the dark I’m going to say its the Red-Leopard-print Lynx
