I am the grandson of Columbus Sargent.
The father of Columbus and John Allen Sargent was John Thomas Sargent. I think his father was William C. Sargent, but sure of this.
Sally's father was John Allen and her mother was Elizabeth Beckham (from her death Certificate). I have additional info on our family, and would love to hear from you. I would also really appreciate any additional information you may have.
Some additional informaion is on our family web site at; http://www.tribalpages.com/tribes?userid=mcbeen

Incidently, we are having a Sargent family reunion in Las Vegas NV a week from Saturday. My sister's family and my family as well as some of the other children of my Mother Dorthy Sargent will be there (Dorthy was the daughter of Columbus your Great Uncle). If you live on the west cost, you may be interested in this.
