I will be glad to exchange info with you. I have a few years invested in research on the family. I can take you back a few more generations, but not far enough back to get to a Nordic connection. Though, I have seen some work done on the family where the researcher found the name 'Brockson'.
Your GG'father William Henry Broxson who m. Gustie Grice was my Dad's 1st cousin and he spoke of the two of them often. Your GGG'father George W. Broxson who married Sarah C.(Sallie) McGowan was my G'mother's oldest brother, so I heard her speak of him. The rest of the way back we have common ancestors.
Please let me know if you are interested in what I have on the family. I would like very much to get some info from you on some of the more recent ones in your family line.
