I understand that George was close to stepfather Henry Teviot Kerr. You can find out more in Burke’s Peerage. Not the same family as the current Lord and Lady Teviot (the title died out) who happen to be genealogists based in West Sussex (where the Linberrys lived/live) and President of the Sussex Family History Group.
I understand that Emma was from a shipping family.
