Yuriy Rockbell

Dr. Yuriy Rockbell (also spelled Urey in the 2003 anime) was the father of Winry Rockbell, the son of Pinako Rockbell, the father-in-law of Edward Elric, and the paternal grandfather of Edward and Winry's unnamed children. He grew up, lived and worked in Resembool as a surgeon alongside his wife, Sarah Rockbell. When the Ishval Civil War reached its peak, the two Doctors Rockbell left their family home in Resembool to help treat the wounded on the front lines. Though both Amestrian, the Rockbells were rather well known in the Kanda region of Ishval for treating the injured on either side of the conflict. Though many, including Doctors Marcoh and Knox, viewed them as a medical inspiration and several Ishvalan people owe their lives to the husband and wife medical team, the Amestrian military officials began to view their humanitarian effort as a nuisance and sought to have them killed.
