Reviewing Helen Stone Woodruff’s research materials. I read letters from Abner Norland who remembers his grandfather, Augustus Swan Aelmore calling Louisa and Alanson Woodruff aunt and uncle. He thought his grandfather’s mother and Louisa might be sisters. Given the Catherine’s last name was Johnson, they may have been sisters-in-law. I have no further information.

Louisa’s daughter Isabelle Katie married James Edward Catlin
James Edward Catlin’s sister was Joanna Elizabeth Catlin
Joanna Elizabeth Catlin married Augustus Swan Aelmore
Augustus Swan Aelmore’s daughter Lillie M married a man named Norland
Lillie was Abner Norlands mother.
