Dear Jerry,

Some family groups appear to observing faster mutation rates. Mine is an
example. The rate in my group (about .004 per transmission event)
appears to be moving about twice the standard rate (about .002 per
transmission event). See the descendants group in my tables which are
descendants of the immigrant ADAM1 and which have Henry numbers
associated with them which shows their relationship to each other.

By the way, was your 2 mutations difference a 1 step change in two
markers, or a two step difference in 1 marker?

Charles
