Tombstone Tuesday - A poetic family legend

By now you should know that my surname is Lamb and that I've been able to trace my direct surname line to Francis Lamb (b. 1796 in Ireland).  There's an old family legend that links this line with a famous Lamb, a link that I am still trying to prove.  You've probably heard of him.  His nickname has appeared in quite a few crossword puzzles through the ages.  That nickname is Elia, and the poet was Charles Lamb.
