Hello Robert. Our limb of the tree has no info. prior to his arrival at Fort Vancouver as an employee of HBC.
I do have digital copies of portraits of him and your great great grandmother Mary Aplin which I can send to you if you email me directly at firstname.lastname@example.org
Curious as to which of George's children is your ancestor.
I am the great grandson of James S Aplin (1867-1937). My daughter Jennifer Hughes of Tualatin, OR is of your generation (great great grand daughter of George and Mary)and has been more active than I in tracing the family tree.
Look forward to hearing from you.
