Since your Y is evidently "European", the only category in the Leiden
table that really matters is the European one, and there were only 42
persons tested. The statistics could be terribly skewed by their
method of choosing subjects. Note that their tables for the other loci
have hundreds to thousands of Europeans tested.

Further note: since the 3-lab comparison shows discrepancies for DYS385
as well, I would be cautious about using those numbers in probing the
Y STR database. I think your original worry about coincidental matches
with other families who also happen to belong to haplogroup 1 (AMH) is
still something to worry about. Try querying the database with DYS385
left blank and see how many matches you find.
