Yes, this helps considerably. Thank you very much! The match seems to be certain with these added bits of information including the two brothers' names (both match my prior information).
I am in the final stages of completing The Coopers in America, 1791-2012, and this opens up the possibility of a whole new line of descendancy extending from a previous dead end in generation three. Hearty thanks are in order. I would also like to credit you properly if possible in the book for your very timely and helpful assistance, if that would suit you.
I only wish there were some way to contact you directly to thank you more properly and find out how you would like to be identified.
