Just found your 2011 message about the Chew and Johnston connection, and would very much like to know if you know where--in VA--your Johnstons were living, and, if they descend--or are related to--Gideon Johnston.
I am a descendant of Larkin Chew and Hannah Roy, and also of Gideon Johnston, of New Kent or Hanover County, Virginia and his wife Ann 'Nancy Ursula Allin. My Johnston line was supposedly originally from Annandale, Scotland, and arrived in the Colonies after first moving to northeast Scotland for some generations.
Do you know where in VA your Johnstons were living? And do you see any connection between our Johnstons?
I have some Johnston research material on this line, that was shared with me, and that I can share.
