Coming in thick and fast now, all below 15 cM, except one.
158 cM over 10 segments. unweighted also 158. Largest segment 29
The same person tested with FT-DNA a couple of years ago, and as you can't upload DNA data to Ancestry from a test done elsewhere, he must have done a new test.
On FT-DNA his match with me is
151 cM with longest segment 30 cM. Is that difference surprising? especially as Ancestry usually adjusts down a bit.
