I can respond with only that my Grandfather settled in the Boston Ma area in the mid to late 1800's. His uncle or brother(unclear of the relationship) owned a blacksmith shop in Dorchester Lower Mills. His last name was Battles. He wanted to put a new sign of his business and the sign maker spelled the name wrong. The name on the sign was Battell. The uncle kept the name and my grandfather also took that name.
Once I can get some family information about my grandfather I will have to look up the Battles family in County Cork Ireland.
Your posting was very interesting. I am glad you had success with your search. As for me I am the last of my father's family alive. I am 50 years old. I have researched my mother's Finnish Family Tree and had great success with that. However, since all my father's family is gone the work is more difficult.
