Yours is a remarkable family;
Lorenzo was 58 when he married Emma.
County death records in 1897 identifies his father as "John H." but do not name his mother. The parents were from NY.
They also indicate that his first wife, Orpha, died in
Clay co., Fla 2-25-1878
Note: There is a John H. McPherson in
Antrim co. but he's not related.
I have a fair amount of information on descendants of
Lorenzo but nothing on his parents.
