Question

I believe the maiden name was Norton not Getchell. Any insight?

Answer 1

The marriage record is imaged at FamilySearch at Records of marriages, births, and deaths, 1834-1892 (familysearch.org) and it lists her name as Lydia N. Getchell.

Answer 2

All of the records I can find, her death, her marriage, her children's births, all indicate her birth name was Getchell.  Still looking for more.

Do you have any evidence for Norton?

Edit to add - Lydia's father Isaac Getchell left a will, naming among his heirs Lydia N Getchell of Topsfield, Maine.
