These pages comprise the descendants and ancestors of Anthony Colby (1605-1660) and his wife Susannah (1610-1689) and most related family branches. Anthony immigrated to America in 1630, was the first Colby in America, and the Colby from whom most present day Colbys living in America originate.

There are many Colbys that have left their mark on America. As America expanded the Colby family moved with it.  We have frontiersmen, pioneers, doctors, teachers, lawyers, statesmen, railroad barons and of course, a few black sheep. There are 92 places in the United States with the Colby name. Included are cities, lakes, schools, and hills.
