Thank you for your interest in the names Brownell and Nelson. It doesn't sound as though any of the people you mentioned are my family. Nelson Cushing Brownell was my grandfather who was born in Wisconsin and died in Montana. It his father Seymour D Brownell that I cannot find. He was born in 1820 somewhere and died in Tomah WI in 1875. He evidently must have been quiet about his origins as there are about 5 birth states listed on various documents and no names. Good luck with your family.
