I went back to my Owens match to check whether we were IBD on the two matching segments. Yes we were. Both were over 500 SNPs
At gedmatch I was able to find cousins who shared a common ancestor at 11 and 12 generations back in Quebec. I noticed the segments I shared with them were IBD, but the segment sizes are generally in the 3cM range. I believe two where in the 5 cM range. This is just one example.
