Hopkins Family

From: caliron@cwnet.com

The photo album of the Hopkins Family has left the family hands, and is, as this is written, in NewCastle. I note with interest the name and picture of Edward Witting Hopkins, with the notation "December, 1872, Initial Stock Holder, S.P.R.R."  Does any one have a family tree of the Hopkins family, or know the relation of Edward W. Hopkins to Mark Hopkins?
Thanks, G J Chris Graves, NewCastle, Cal.
