My Grandmother Hood had a family crest, but the mistake she made was looking up the Hood description and my Grandfather (Mother's side) said words to the effect ... that is not the bird in the Hood description, that is not a Hood crest.
EDIT: I feel I need to get this properly identified as the bird is stood on something and grasping the other side with a claw.
The mystery for me now, is how did Hood acquire it.
Regards Mark
Edit: You are making the same mistake my Grandmother made 50 years ago, looking at the Hood description.
