From: "Rob and Bonnie Robinson" 
The Ferguson line I am working on comes from NY and disperse through MI, NY,
NE, KS, CO and WA. This line might be related to the Fergusons of
Dutchess/Columbia County, NY of the late 1700s and early 1800s. Also might
be linked to the Fergusons of Montgomery County, NY.

It has a list of all the Ferguson I have on this line(with related
families).

Thanks
