A descendant had the answer… and he left a comment.
The unknown woman in Archie and Anna Quesnell’s wedding photo is Delia Rose Martel, John and Anna’s sister.
John Martel and Delia Rose Martel
Anna Martel and Archie Quesnel
This is Delia Rose’s memorial on Find a Grave.
I wish I had more pictures of Delia Rose and her husband Roy L. Owen.
This is what I have for Roy…
I have linked them both for descendants who would one day search Find a Grave.
I will even post Delia Rose’s picture.
Like I did for Mary Masta and her husband Joseph Martel.
