Mary Ann Norton

I'm guessing at her date of birth based on the census information Anne Richard found. That 1880 census lists her as being 56 years old at the time.

Her father had a farm near Dublin. She had seven brothers (per Jane). Martin left the seminary to marry her.

Claire Crabtree has notes indicating she was from Dublin.

After Martin's death, she stayed in Phillipsburg but eventually moved to New York City.
