Here is a fun little investigation, if somebody has time and family interest. I received this message. Below it is my speculative response. I have the private contact info on file, if this turns up any results, and interested family descendants.
I have a miniature portrait on ivory of "John Duryea New York 1778"
in a gold oval locket case. There is basket weaved hair on the
reverse view. The portrait is of a child age 7-10.
Since you manage the Duryea WikiTree page, I was wondering if you
knew of any descendent who might like to purchase the locket?
My mother-in-law purchased the locket about 30 years ago from
one of the McGraw brothers of McGraw Hill publishing fame.
Thanks for any assistance.
Hi Vaughn, that is very cool.
It might be best traceable through the lineage of the McGraw family, since it probably came down as a family heirloom.
So first step is to identify precisely who had it before your mother. Since the McGraw publishing family are famous, that should not be difficult, to identify which McGraw family branch it was, and find their ancestors, to see if they simply trace back to Duryea.
