I have seen some posts regarding the name Jehu Pollard.
I found this name in a tree for my husband's grandmother. Her Jehu Pollard had the alternate name of Joshua. He was the son of William Pollard and Jone Coome who were married on 2 Feb 1647 at Mawnan but that could be a mis-spelling.
Not sure how common that name was. It is an interesting one.
