Harfang Longbottom
On Rowling's Black Family Tree, a Harfang Longbottom married Callidora Black, daughter of Arturus Black. No dates for Harfang, but Callidora was born in 1915 and appears to still be alive (no death date) (BFT).
Name origen: In French, an 'Harfang des neiges' is a snowy owl.

maybe far fetched but it made me think.
