My gggrandfather,Patrick Herrington,came to Boston in 1847 from Cork. I cannot find any info before such as hometown,etc. He named his only son, William Flem. Flem named his son, John Wesley alexander Herrington. Another John Herrington came the same route in 1847 and fought in the same unit from alabama in the civil war. both were captured in the Battle of Franklin TN. John died/buried in POW camp in Ohio, Pat survived and returned to alabama. Have you ever heard any "stories" that might show a link?? (forgive my typing,had surgery on hand.)
