Tim:

Have you seen this one?:

Perhaps Ugo or someone else from SMGF could give us an update on their
autosomal testing and public database.

A combination of the 23andMe, deCodeme and SMGF material would be
ideal from a genetic genealogy standpoint. We could do it on our own
as a coordinated project of persons in SMGF and the other projects.

One problem with SMGF is their reliance on the Ancestral FIle when
they "verify" pedigrees. Our Y DNA testing has proven my Ball line is
not related to Col William Ball, but the extended pedigree in the SMGF
still links John Ball of Stafford and Fairfax Co.s VA to Col William
Ball.
