“a code for geographic “residence of mother” to the left of the box.”
And the printed “?” left resdience of the mother?
To my eyes it looks like a handwritten “2” next to geographic residence of mother. Below that, I don’t know what that mark is — it is not clearly a type-set question mark to my eyes. The Nordyke certificate does not appear to have anything where that is. Perhaps it is the edge of a punch-hole, I can’t tell for sure.
