Nearly everything I have seen which links him to his father
only names this person Peter. But it seems be be the same person
as George Peter. (The age on the census matches, named relationships
to other Gilchrist family members, etc.).
Also, papers of Elisha Challen Scott
(as viewed and possessed by Trudy Morrison Heiman)
had this person down as George Peter. I found this out after I came
to the same conclusion independently.
Since many of the female Gilchrists took on an extra
first name, e.g. Mary Jane for Jane, why couldn't this Peter take on
George as extra 1st name?
