Rosenblatt is a surname of German and Jewish origin, meaning "rose leaf".
(Herman Rosenblatt married Fannie Chelec, the daughter of Joseph and Rosa Chelec, the sister of Meyer Chelec and Rae Chelec Solomon. Fannie Chelec immigrated from Roumania to the port of Norfolk, VA, in the early 1900s with her family. Herman and Fannie Chelec Rosenblatt had two children, Sam Rosenblatt of Norfolk and Virginia Beach, VA, and Helen Rosenblatt Caplan of Norfolk. Sam and Trudy Rosenblatt had 2 or 3 children, including Chucky (Charles) Rosenblatt. Helen and Lou Caplan were the parents of Harry Caplan, who went to live in Japan, and Marilyn Caplan of Norfolk. Marilyn Caplan married Leonard Doline and they had 2 (?) children. I think their son is Robert Doline.)
