I was also under that opinion, but the DNA tests are showing that there are at least two distinct groups and that one of those groups the relationship is back MANY generations. Carsons who have done the DNA test are understandably R1b1, which you would expect from Ireland and Scotland, but we also have a set of I Carsons, which are Nordic. This group was likely started from a Viking invader, so it doesn't mean that those Carsons immigrated to America from Sweden (my first very confused thought!). DNA results (to date) here: http://www.worldfamilies.net/surnames/c/carson/results.html I am currently working on expanding my DNA knowledge so I can better understand how far back these relationships might be. It's not exact as you can't be sure when a sequence will mutate, but they have models that they have followed. --- [email protected] wrote: > It is the OPINION of many Carsons that all are related.
